Synthesis of chiral palladium oxazolidine and imine complexes: Investigation the oxazolidine-imine conversion by DFT method

Reaction of 2-pyridinecarboxaldehyde with L-Alaninol (as a chiral amine) or 2-amino-2-methyl-1-propanol (AMP) in the presence of PdCl2 produced the new and attractive palladium(II) complexes which were synthesized by in situ method. The presence of an extra methyl group in AMP other than L-Alaninol induced the different chelating mode and, therefore, several structurally different palladium complexes obtained. Correspondingly, the chiral amine with PdCl2 produced the imine product, (Iminol (1)), and an oxazolidine compound (Imizol (1′)) as minor product. Also, the use of AMP in formation of palladium complexes led to the synthesis of imine (Ampynol (2)) and oxazolidine (Ampyzol (3)) complexes. Besides utilizing of crystallization technique for the separation of the isomers, elemental analysis (CHN), FT-IR, H-1 and C-13 NMR spectroscopies were used for characterization of the synthesized compounds. In addition, structures of palladium complexes Iminol and Ampyzol were identified by single crystal X-ray diffraction method and investigation of the equilibrium between imine and oxazolidine complexes were carried out by DFT method. The in vitro studies revealed that the compounds have considerable cytotoxicity against human MCF-7 and HeLa cancer cell lines. (C) 2018 Elsevier Ltd. All rights reserved.

Metal-Free Synthesis of Oxazolidine-2,4-diones and 3,3-Disubstituted Oxindoles via ICl-Induced Cyclization

A metal-free method for the construction of oxazolidine-2,4-diones and oxindoles was discussed. Using iodine monochloride (ICl) as both the reaction promoter and iodide source, the iodolactonization of N-Boc acrylamides proceeded readily and provided the corresponding iodo oxazolidine-2,4-diones and oxazolidin-2-ones in good isolated yields. The obtained oxazolidine-2,4-diones can be used as key intermediates in the synthesis of toloxatone. When N-alkyl-N-arylacrylamide derivatives were subjected to the same reaction, iodocarbocyclization products 3,3-disubstituted oxindoles were obtained. The obtained oxindoles can be used as key intermediates in the synthesis of the alkaloids (+/-)-esermethole and (+/-)-physostigmine.

A novel one-pot, two-step synthesis of N-acyl-1,3-thiazolidines and N-acyl-1,3-oxazolidines as potential double prodrugs of formaldehyde

A convenient and general one-pot, two-step protocol to prepare both N-acyl-1,3-thiazolidines and N-acyl-1,3-oxazolidines from formaldehyde, fatty acyl chlorides, and natural a-amino acids has been performed for the peculiar case of formaldehyde. In the presence of triethylamine to promote both the ring-forming process and the amide bond formation, subsequent addition of the acyl donor proved to be efficient to trap the preformed stable formaldehyde-derived 1,3-thiazolidine or the transient 1,3-oxazolidine using an appropriate ratio of formaldehyde.

Induction of Herbicide Detoxifying Enzyme in Maize by Chiral 3-Dichloroacetyl Oxazolidine

Safeners are important tools used to ensure to safe useof herbicide. The aim of this paper is to evaluate the protective effect of four safeners (R-28725, 3-dichloroacetyl oxazolidine and its two optical isomers) and investigate the mechanism of herbicide detoxication by safener. Laboratory studies were conducted to evaluate the effectiveness of safeners for protecting maize from the residues of preemergent herbicide fomesafen in Northeast Agricultural University, China. Physiological and biochemical tests were herein conducted under laboratory conditions, by using seed treatment with safeners and soil treatment with fomesafen, respectively. R-28725 provoked high glutathione level, glutathione-Stransferase activity and affinity of glutathione-S-transferase than other safeners, but R-isomer treatment resulted in complete reversal of injury caused by fomesafen.

Estimation of Circulating Drug Metabolite Exposure in Human Using In Vitro Data and Physiologically Based Pharmacokinetic Modeling: Example of a High Metabolite/Parent Drug Ratio

(R)-4-((4-(((4-((tetrahydrofuran-3-yl)-oxy) benzo[d] isoxazol-3-yl) oxy)methyl) piperidin-1-yl) methyl) tetrahydro-2H-pyran-4-ol (TBPT), a serotonin-4 receptor partial agonist, is metabolized to two metabolites: an N-dealkylation product [(R)-3-(piperidin-4-ylmethoxy)-4(( tetrahydrofuran-3-yl) oxy) benzo[d] isoxazole (M1)] and a cyclized oxazolidine structure [7-(((4-(((R)-tetrahydrofuran-3-yl) oxy) benzo [d] isoxazol-3-yl) oxy) methyl) octahydro-3H (M2)]. After administration of TBPT to humans the exposure to M1 was low and the exposure to M2 was high, relative to the parent drug, despite this being the opposite in vitro. In this study, projection of the plasma metabolite/parent (M/P) ratios for M1 andM2 was attempted using in vitro metabolism, binding, and permeability data in static and dynamic physiologically based pharmacokinetic (PBPK) models. In the static model, the fraction of parent clearance yielding the metabolite (which also required taking into account secondary metabolites of M1 and M2), the clearance of the metabolites and parent, and an estimate of the availability of the metabolites from the liver were combined to yield estimated parent/metabolite ratios of 0.32 and 23 for M1 and M2, respectively. PBPK modeling that used in vitro and physicochemical data input yielded estimates of 0.26 and 20, respectively. The actual values were 0.12 for M1/TBPT and 58 for M2/TBPT. Thus, the ratio for M1 was overpredicted, albeit at values less than unity. The ratio for M2/TBPT was underpredicted, and the high ratio of 58 may exceed a limiting ceiling of the approach. Nevertheless, when considered in the context of determining whether a potential circulating metabolite may be quantitatively important prior to administration of a drug for the first time to humans, the approaches succeeded in highlighting the importance of M2 (M/P ratio >> 1) relative to M1, despite M1 being much greater than M2 in vitro.

Encryption and authentication of security patterns by ecofriendly multi-color photoluminescent inks containing oxazolidine-functionalized nanoparticles

Counterfeiting of confidential documents has been a costly challenge for banks, companies, and customers. Encryption of invisible security marks, such as barcodes, quick response codes, and logos, in national or international confidential documents by high-security anticounterfeiting inks is the most significant solution for counterfeiting problems. Ecofriendly multi-color photoluminescent anticounterfeiting inks based on highly-fluorescent polymer nanoparticles functionalized with new oxazolidine derivatives were developed for the fast and facile encryption of security labels on cellulosic documents, such as paper currency, passport, and certificate. Depending on the polarity of functionalized polymer nanoparticles, a wide range of colors and fluorescence emissions were observed as a result of polarpolar interactions between the oxazolidine molecules and surface functional groups of the nanoparticles. The fluorescent polymer nanoparticles showed spherical, vesicular, and cauliflower-like morphologies resulted from different surface functional groups. Functional polymer nanoparticles displayed high stability and printability on cellulosic substrates due to hydrogen bonding interactions. The highly-fluorescent polymer nanoparticles were also used to prepare anticounterfeiting inks with different colors and fluorescence emissions. All the ecofriendly polymeric anticounterfeiting inks were loaded to stamps with specific marks, and then applied to different confidential documents. Printed labels displayed highly intense fluorescence emission in different colors (green, orange, pink, and purple depending on the matrix polarity) under UV irradiation (365 nm). These water-based multi-color fluorescent anticounterfeiting inks with highly intense, bright, and sensitive fluorescence emission have potential applications in encryption and authentication of security patterns.

CuI/CuBr2-catalyzed decarboxylative/A(3) reaction of propiolic acids for the facile synthesis of 1,4-diheterocycle-2-butynes

A novel and efficient microwave-assisted protocol to 1,4-diheterocycle-2-butynes was successfully developed. The method is based on one-pot copper-catalyzed A(3) reaction/decarboxylative coupling of a propiolic acid, a formaldehyde, and a 1,2- or 1,3-amino alcohol. This multicomponent coupling reaction provides a straight forward access to introduction oxazolidine or 1,3-oxazinane at the 1,4-position of a but-2-yne from readily available starting materials. 1,4-Diheterocycle-2-butynes with diverse substitution patterns are obtained in moderate to good yields.

Microwave-assisted synthesis of some hybrid molecules containing penicillanic acid or cephalosporanic acid moieties and investigation of their biological activities

Ethyl 4-amino-2-fluorophenylpiperazin-1-carboxylates containing a 1,3-oxazol(idin)e, 5-thioxo-1,2,4-triazole, 1,3,4-thiadiazole, 5-thioxo-1,3,4-oxadiazole, or 1,3-thiazole nucleus were obtained starting from ethyl piperazine-1-carboxylate (1) by several steps. The treatment of amine, 3 or hydrazide, 9 with several aromatic aldehydes generated the corresponding arylmethyleneamino (3a-f) or arylidenehydrazino (12a-c) compounds. The Mannich reaction between the 1,2,4-triazole or 1,3,4-oxadiazole compounds and 7-aca produced cephalosporanic acid derivatives. Penicillanic acid derivatives were obtained when 6-apa was used in the Mannich reactions. The synthesized compounds were screened for their antimicrobial, antilipase, and antiurease activities. Some of them were found to possess good-moderate antimicrobial activity against the test microorganisms. Two compounds exhibited antiurease activity, and four of them displayed antilipase activity.

The safener effect of chiral derivatives of 3-dichloroacetyl oxazolidine against haloxyfop-P-methyl-induced toxicity in maize

Herbicide safener, a diverse group of chemicals, is an important tool used to protect plants from herbicidal injury. With the aim of decreasing drift injury of haloxyfop-P-methyl to sensitive plants, the protective effect of four safeners (R-28725, 3-dichloroacetyl oxazolidine and its two optical isomers) was evaluated. Physiological and biochemical tests were conducted under laboratory conditions in Northeast Agricultural University, China, by using seed treatment with safener and soil treatment with haloxyfop-P-methyl, respectively. The maize seeds treated with these safeners were safe from haloxyfop-P-methyl treatment. A positive correlation between growth level and endogenous glutathione (GSH) content, glutathione S-transferases (GST) activity was observed in this research. Enhancement of GSH content, GST activity and affinity of GST to 1-chloro-2,4-dinitrobenzene (CDNB) in maize treated by R-28725 was maximum. However, the detoxification of herbicide was not accompanied by the increase of acetyl-CoA-carboxylase (ACC) activity in maize.

Dynamical Behavior and Second Harmonic Generation Responses in Acido-Triggered Molecular Switches

Second-order nonlinear optical molecular switches are systems displaying marked variations of their second harmonic generation (SHG) responses upon external stimulation. In this article, we combine a multiscale computational method and experimental characterizations to provide a full description of the SHG responses of molecular switches built from the association of the indolino-oxazolidine unit to a bithiophene donor. In chloroform solutions, the addition of trifluoroacetic acid triggers the switching from a neutral closed form to a protonated open form, making an ion pair with the trifluoroacetate counterion and induces a strong enhancement of the SHG responses. The numerical simulations (i) evidence how the large and rapid thermally induced geometrical fluctuations lead to broadening the SHG responses distributions, making even difficult the determination of their sign, (ii) rationalize the variations of these responses as a function of the closure/opening of the oxazolidine ring and of the nature of its chemical substitution, and (iii) call into question common assumptions employed when analyzing the experimental SHG responses.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 84793-24-8 help many people in the next few years. Computed Properties of C16H19NO5.
