Fluorescent triazolyl spirooxazolidines: Synthesis and NMR stereochemical studies

Carbon-heteoratom chemistry is a method of choice for rapid construction of complex molecules. In the recent decade, its various applications flourished thanks to the click chemistry approach. Herein, we use a combination of C-X bond formation reactions to complete the synthesis of 1,2,3-triazolyl spirooxazolidines, bearing the fluorenylmethoxycarbonyl (fmoc) substituent. Thanks to the application of 2D-NMR spectroscopic methods and a multilevel computational approach, including a medicinal chemistry – inspired conformational search, PM7 semiempirical and DFT-based geometry optimization finalized with DFT-GIAO NMR shielding constant calculation, we were able to investigate the conformational space and assign cis/trans configuration in complex NMR spectra. For the obtained fmoc derivatives we recorded UV-VIS absorption and emission spectra. The obtained compounds contain pharmacophoric groups characteristic for endocannabinoid system modulators- CB1 receptor ligands or FAAH inhibitors. (C) 2019 Elsevier B.V. All rights reserved.

Synthesis of unprecedented steroidal Spiro heterocycles as potential antiproliferative drugs

Herein we report the straightforward preparation of novel conformationally-restricted steroids from trans-androsterone and estrone, decorated with spiranic oxazolidin-2-one or 2-aminooxazoline motifs at C-17 as potential antiproliferative agents. Such unprecedented pharmacophores were accessed using an aminomethylalcohol derivative at C-17 as the key intermediate; reaction of such functionality with triphosgene, or conversion into N-substituted thioureas, followed by an intramolecular cyclodesulfurization reaction promoted by yellow HgO, furnished such spirocycles in excellent yields. Title compounds were tested in vitro against a panel of six human tumor cell lines, named A549 (non small cell lung), HBL-100 (breast), HeLa (cervix), SW1573 (non-small cell lung), T-47D (breast) and WiDr (colon), and the results were compared with steroidal chemotherapeutic agents (abiraterone and galeterone); the A-ring of the steroidal backbone, the nature of the heterocycle and the N-substituents proved to be essential motifs for establishing structure-activity relationships concerning not only the potency but also the selectivity against tumor cell lines. Estrone derivatives, particularly those bearing a spiranic 2-aminooxazoline scaffold were found to be the most active compounds, with Gl(50) values ranging from the low micromolar to the submicromolar level (0.34-1.5 mu M). Noteworthy, the lead compounds showed a remarkable increase in activity against the resistant cancer cell lines (T-47D and WiDr) compared to the anticancer reference drugs (up to 120-fold).

Synthesis and structural characterization of bis[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]copper(II) dichloride and bis[(4S,5R)-4-methoxycar-bonyl-5-methyl-2-oxazoline]-[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]ruthenium(III) trichloride

In the reaction of N,N’-methylenebis[(4S,5R)-4-methoxycarbonyl-5-methyloxazolidine] (1) with CuCl2 or RuCl3 in alcoholic solvents novel complexes, bis[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]copper(II) dichloride (2) and bis[(4S, 5R)-4-methoxycarbonyl-5-methyl-2-oxazoline]-(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidineruthenium(III) trichloride (3), respectively, were isolated and fully characterized by X-ray crystallography. In these reactions, which occurred under mild conditions, ligand 1 was cleaved at the bridging aminal position and degraded to (4S, 5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine 5. The trigonal bipyramidal Cu complex 3 contains two such oxazolidine ligands coordinated in different ways. One is bonded in a monodentate fashion via the nitrogen atom of the five-membered ring, the other binds as a bidentate ligand, additionally using the carbonyl oxygen of the ester group. In the octahedral Ru complex 4 there are one oxazolidine ligand 5 and two oxazoline ligands 6. Thus, in the synthesis of 4 the carbon atom between oxygen and nitrogen in the oxazolidine ring was partly oxidized from the half-aminal status to the carboxamide status. (C) 2012 Elsevier B. V.

Convenient Synthesis of Pyrimidine acyclo-2,2 ‘-anhydronucleosides and their Exploitation Toward Selected N-nucleophiles

A new method of the synthesis of 2-(hydroxymethyl-2H-oxazolo[3,2-a]pyrimidin-7(3H)-ones, commonly known as pyrimidine acyclo-2,2′-anhydronucleosides, was developed. Under the Mitsunobu reaction conditions, 5-substituted 1-(3′-alkoxy-2′-hydroxypropyl)uracil derivatives underwent an intramolecular cyclization to the corresponding 2-alkoxymethyl-2,3-dihydro-7H-oxazolo[3,2-a]pyrimidin-7-ones. The various synthetic methods have been demonstrated in the reactions with several N-nucleophiles. Importantly from the mechanistic point of view, in the case of 6-bromo-2-(hydroxymethyl)-2H-oxazolo[3,2-a]pyrimidin-7(3H)-one treated with chiral isocyanate the inversion of configuration at the C-4’ carbon atom accompanied by the oxazolidine ring opening was observed.

Microenvironments induced ring- closing of halide salts of oxazolidines: a rare inverse proton gradient process and its application in water- jet rewritable paper

Proton gradient reactions are common, but those with inverse proton gradients are rare. Inspired by the phenomenon that stomach can release acid with microenvironment changes, an inverse proton gradient process along with a ring-closing of the precursors of oxazolidine molecular switches (i.e., ROF(+)X(-)s) was achieved within specific microenvironments both in solution and on solid substrate. Nucleophilicity and concentration of solution were found playing important roles in this process. Furthermore, benefits from this ring-closing process arose from inverse proton gradient, a potential application of ROF(+)X(-)s replacing their akalization productsring-closed forms (RCFs) of oxazolidines in water-jet rewritable paper (WJRP) was developed. Influence of dissolving solvent and drying temperature on hydrochromic performances of ROF+X- based WJRP were inspected and compared to its corresponding RCF based WJRP. Results indicate that the former outperforms the latter in color depth, coloration speed and retention time. The water-jet prints on ROF+X- based WJRP exert excellent legibility, resolution, uniformity, and repeatability. This research achievement will not only promote the industrialization of oxazolidines derivatives based WJRP by greatly reducing production costs from a perspective of synthetic industrialization, but may also provide a reference for better understanding of similar microenvironment-induced phenomena of inverse proton gradient in complex biosystems.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 84793-24-8, you can contact me at any time and look forward to more communication. SDS of cas: 84793-24-8.

Synthesis of polyoxazolidines and their application in moisture-curable polyurethane

A series of polyoxazolidines based on monofunctional oxazolidine were designed and successfully synthesized by transesterification reaction. Their structures were characterized by H-1 NMR, C-13 NMR, FI-IR, ESI-MS, and elemental analysis. FI-IR spectroscopy was used to study the kinetics of oxazolidines hydrolysis reactions. Furthermore, the applications of resulting oxazolidines as latent curing agents in single-component polyurethane (SPU) systems were investigated. The experimental results showed that the pure SPU specimen cured under atmospheric moisture formed lots of foaming and presented serious swelling. In contrast, the SPU specimens including oxazolidines and latent curing agents displayed considerable enhancement in the mechanical properties, apparent performance, and curing rate. Compared with SPU-OXi curing samples, the tensile strength of the SPU-OX2 reached up to 1.78Mpa, and the elongation at break increased to 533.0%, resulting from the dual effects of the high cross-linking density and the urethane group in OX2.

Acanthomanzamines A-E with New Manzamine Frameworks from the Marine Sponge Acanthostrongylophora ingens

Five new manzamine alkaloids, acanthomanzamines A-E, were isolated from the marine sponge Acanthostrongylophora ingens. Acanthomanzamines A and B are the first examples, containing a tetrahydroisoquinoline instead of a beta-carboline in manzamine-related alkaloids. Acanthomanzamine C contains a hexahydrocyclopenta[b]-pyrrol-4(2H)-one ring that may be converted from an eight-membered ring in manzamine A. Acanthomanzamines D and E have an additional oxazolidine and 2-methyloxazolidine rings, respectively, which fuse to the manzamine skeleton.

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.

Decarboxylative Generation of 2-Azaallyl Anions: 2-Iminoalcohols via a Decarboxylative Erlenmeyer Reaction

Condensation between the tetrabutylammonium salt of 2,2-diphenylglycine and aldehydes results in a decarboxylative Erlenmeyer reaction, affording 1,2-diaryl-2-iminoalcohols as a mixture of diastereomers in good yields. The diastereomeric ratio shifts over time, with the anti diastereomer and the syn oxazolidine tautomer serving as the kinetic and thermodynamic products, respectively. Addition of Lewis acids can catalyze the rates of reaction and product equilibration. The results highlight the stereochemical promiscuity of 1,2-diaryl-2-iminoalcohols in the presence of Lewis acids and Bronsted bases.
