Fluorescent Recognition of Functional Secondary Amines in the Fluorous Phase

In a fluorous solvent (perfluorohexane, FC-72), a perfluoroalkyl-substituted 2-hydroxy-1-naphthaldehyde (1) was found to show greatly enhanced fluorescence when treated with certain functional secondary amines but little fluorescence response was observed with unfunctional amines as well as functional primary and tertiary amines. The study of the reaction of 1 with 2-methylamino ethanol (8) reveals a facile cyclocondensation of the aldehyde group of 1 with this 1,2-amino alcohol to form a 5-membered ring oxazolidine product which turns on the fluorescence. The reaction of 1 with the amino alcohol was found to be more favorable in the fluorous solvent than in a common organic solvent. The use of the fluorous phase-based fluorescence measurement in this work provides a potentially more sensitive as well as selective method in amine sensing.

Flavone-Nitrogen Heterocycle Conjugate Formation by 1,3-Dipolar Cycloadditions

Azomethine ylides generated in situ from the reaction of N-[2-,3- and 4-(chromon-2-yl)phenyl] glycine and paraformaldehyde can be trapped with dipolarophiles in 1,3-dipolar cycloaddition reactions to yield flavone-nitrogen heterocycle dyads. These azomethine ylides proved to be reactive with electron-poor dipolarophiles, affording the expected adducts. The use of microwave irradiation as an alternative source of heating has significant advantages and allows a reduction of both reaction time and temperature. The use of benzaldehydes as dipolarophiles afforded flavone-oxazolidine dyads, and the results indicate that electron-withdrawing groups in the para position of the benzaldehyde increases the dipolarophile reactivity. This work was also extended to the use of meso-tetrakis(pentafluorophenyl) porphyrin as a dipolarophile, allowing new flavone-dihydroporphyrin conjugates to be prepared.

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 6704-31-0 help many people in the next few years. Quality Control of Oxetan-3-one.

A Novel Method for Preparation of Linezolid, (S)-N-((3-(3-Fluoro-4-Morpholinophenyl)-2-Oxo-5-Oxazolidinyl) Methyl) Acetamide

Background: Linezolid (I) [(S)-N-((3-(3-fluoro-4-morpholinophenyl)-2-oxo-5-oxazolidinyl) methyl) acetamide] is a synthetic antibiotic used for the treatment of serious infections caused by grampositive bacteria that are resistant to other antibiotics. Linezolid empirical formula is C(1)6H(20)FN(3)O(4) and its molecular weight is 337.35. It is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). The main uses are infections of the skin and pneumonia, although it may be used for a variety of other infections. Linezolid was discovered in the 1990s by a team at Pharmacia and Upjohn Company and first approved for use in 2000. Lohray et al., in 1999, have reported a synthetic method for Linezolid starting from D-mannitol, the chemical synthesis of Linezolid by alternate route has attracted several research groups in the past 15years. Methods: An improved and economically viable process is described to prepare Linezolid wherein methyl 3-fluoro-4-morphinolino phenyl carbamate (V) is reacted with R-epichlorohydrin in the presence of n-butyllithium in hexane to obtain (R)-5-(chloromethyl)-3-(3-fluoro-4-morpholinophenyl) oxazolidin-2-one (IV) which reacts with potassium phthalimide in presence of polar solvent to give (S)-2-[3-(3-3-fluoro-4-morpholin-4-yl-phenyl)-oxazolidine-5-yl methyl]-isoindole-1,3-dione (III), which is subsequently converted to Linezolid. Results: Linezolid was obtained via only four steps with yield 90% and high purity. This process avoids formation and use of sensitive intermediates. It is an improved process for the preparation of an intermediate (R)-5-(chloromethyl)-3-(3-fluoro-4-morpholinophenyl) oxazolidin-2-one (formula IV). Conclusion: Linezolid was successfully synthesized from (3-fluoro-4-morpholin-4-yl-phenyl)-carbamic ester via R-epichlorohydrin and potassium phthalimide and developed new intermediate (5R)-5-chloromethyl-3-(3-fluoro-4-morpholin-4-yl-phenyl) oxazolidin-2-one (IV). The present method relates to a novel, cost effective and industrially viable process. Thus, the process described is less cumbersome by way of reduced reaction stages, high purity and quantity of the yield. In comparison with previously reported synthetic strategies, this novel approach is believed to be the shortest and the most efficient synthetic route to date.

Design, synthesis, and anticancer evaluation of some novel thiourea, carbamimidothioic acid, oxazole, oxazolidine, and 2-amino-1-phenylpropyl-2-chloroacetate derived from L-norephedrine

A novel series of thiourea, carbamimidothioic acid, 4, 5-dihydrooxazole-2-thiol, oxazolidine-2thine, and 2-amino-1-phenylpropyl-2-chloroacetate derivatives was designed and synthesized using 2-amino-1-phenylpropan-1-ol (L-norephedrine) as a strategic starting material. The structures of the newly synthesized compounds were established by elemental analyses, IR, and H-1 NMR and C-13 NMR spectral data. The compounds were evaluated for their in vitro anticancer activity against various cancer cell lines. The corresponding acetamide, carbamimidothioic acid, and 2-2-amino-1-phenylpropyl-2-chloroacetate derivatives showed almost the same activity as the standard drug doxorubicin against human breast cancer cell line (MCF-7). Also, the acetamide and 2-thioxoimidazolidin-4-one derivatives exhibited higher activity than the reference drug doxorubicin against human colon cancer cell line (HCT 116).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 16251-45-9, in my other articles.

Solvent and Base in One: Tetra-n-butylammonium Acetate as a Multi-Purpose Ionic Liquid Medium for Ru-Catalyzed Directed Mono- and Di-o-C-H Arylation Reactions

Ru-catalyzed directed o-C-H arylation reactions of 2-phenylpyridine, N-phenylpyrazole, acetophenone N-(p-methoxyphenyl)imine, and 2-phenyloxazoline proceed in good to excellent yields with a number of functionalized aryl and heteroaryl bromides in neat Bu4NOAc at 120 degrees C. The acetate ion acts as the base and the relatively low melting point Bu4N salts (a mixture of acetate and bromide) behave as an ionic liquid. Arylation reactions of 2-phenyloxazoline proceed with concomitant oxazolidine cleavage to give 2-(N-acetylamino)ethyl benzoates promoted by side product CH3COOH. The dual-purpose ionic liquid medium is compatible with both ligandless Ru for di-arylation (optimal pre-catalyst: RuCl3xH2O) and Ru-phosphane (optimal pre-catalyst: [RuCl2(p-cymene)](2)/P(p-Tol)(3) 1:4) catalysts (1-5 mol-%) for selective mono-arylation.

Fe-catalyzed synthesis of substituted N-aryl oxazolidines

A novel iron-catalyzed synthesis of substituted N-aryl oxazolidines was developed via C-N bond formation and methylenation. The reaction of aryl hydroxylamines with allyl alcohols, in the presence of formaldehyde or its equivalents, afforded variety of oxazolidine heterocycles in very good yields. This catalytic method is most effective for para-substituted aryl hydroxylamines and 3-methyl allyl alcohols. Furthermore, acid catalyzed demethylenation of oxazolidines allowed access to N-aryl amino alcohols in good yields.

Polyols and Rigid Polyurethane Foams from Cashew Nut Shell Liquid

Cashew nut shell liquid (CNSL) is a natural aromatic oil consisting of a mixture of phenolic structures with a carboxyl group in ortho position and substituted in meta position with a hydrocarbon chain of 15 carbon atoms. The major component of CNSL is anacardic acid (90 %), which is easily decarboxylated to cardanol by distillation. The present work describes the synthesis of new biobased Mannich polyols for rigid polyurethane foams in two steps: synthesis of Mannich bases by reacting phenolic ring of cardanol with N-(2-hydroxyethyl)-1,3-oxazolidine followed by alkoxylation reactions. The polyols were characterized by wet methods (hydroxyl numbers, viscosity, acid value, density, water content, iodine value etc.), spectroscopic methods (FT-IR, H-1 NMR and C-13 NMR) and by Gel Permeation Chromatography. The Mannich polyols from cardanol are excellent replacements for petrochemical derived Mannich polyols based on nonyl phenol. Cardanol-based polyols were used successfully for the preparation of rigid polyurethane foams of good physical-mechanical and fireproofing properties.
