Palladium(II)-Catalyzed C(sp (3) )-H Activation of N,O-Ketals towards a Method for the -Functionalization of Ketones

A method for the formal -functionalization of aliphatic ketones via a palladium-catalyzed sp (3) C-H activation pathway is reported. An N,O-ketal directs an aliphatic C-H carbonylation to form -lactams which upon hydrolysis generate -keto carboxylic acids. This C-C bond-forming reaction is tolerant of a range of functional groups, enabling the synthesis of a range of synthetically important building blocks. Furthermore, the concepts underlying this transformation have also enabled the development of a related C-H alkenylation process to highly functionalised heterocycles.

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.

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.

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.

Microwave-assisted and conventional synthesis of novel antimicrobial 1,2,4-triazole derivatives containing nalidixic acid skeleton

Carbothioamides 4a,b, obtained from nalidixic acid, were converted to the corresponding 1,3-thiazolidine derivatives 5a,b by cyclocondensation with 2-bromo-1-(4-chlorophenyl) ethanone. Treatment of 4a,b with base afforded 1,2,4-triazoles 6a,b. The synthesis of 1,3-oxazolidine 7 was performed by the reaction of compound 4a with ethyl bromoacetate. Treatment of 4a with acid produced 1,3,4-thiadiazole 8. The reaction of compounds 6a and 6b with several heterocyclic amines in the presence of formaldehyde gave the corresponding Mannich bases 9-15 containing various pharmacophore groups. Conventional and microwave-assisted methods were used for the synthesis. The effect of an acid catalyst on Mannich reactions was investigated. The structures of the newly synthesized compounds were elucidated on the basis of H-1 NMR, C-13 NMR, FTIR, EIMS techniques, and elemental analysis. All compounds were screened for their antimicrobial activity.

Tuning the strain effect to induce selectivity through intramolecular nitrene insertion into an adjacent methoxy C-H bond leading to form a new benzoxazole: experimental and computational studies

Pyrolysis of azido-meta-meconine yields only a single product 1D, which has been characterized spectro-scopically (H-1 NMR, C-13 NMR, HSQC, DEPT & MS). These results reveal that the fused five-member lactone ring can influence the product selectivity. The DFT calculations suggest the formation of favourable oxazolidine intermediate compared to azirine (1Z) and ketenimine (1H) intermediates. The isodesmic analysis showed that the fused lactone aryl nitrene (1N) would have more strain to form azirine (1Z) intermediate than the corresponding aryl nitrene (1M). (C) 2016 Elsevier Ltd.

Palladium-catalyzed oxamidation of alkenes: A new approach to benzoxazolidines

A novel palladium catalyzed protocol for the synthesis of benzoxazolidine by the reaction sulfamido-phenol and terminal alkene was developed. This oxamidation process is simple and does not require any ligand, base or inert atmosphere for the overall transformation. From control experiments, it is apparent that the cross-coupling reaction proceeds with initial formation of enesulfonamide which undergoes nucleopalladation by the intramolecular annulation and subsequent protodepalladation by TsOH to afford the benzoxazolidine.

Effect of Ionic-Strength and pH Value in Mobile Phase on Enantio-Separation of BSA High Performance Liquid Chromatography Column

BSA chiral columns were prepared based on column modification method with carbonyl imidazole as cross-linker. Enantioseparation of tryptophan, pidotimod and 4-phenyl-1,3-oxazolidine-2-thione (L-ben) was obtained on the BSA chiral column by HPLC. The effects of pH values and ionic strength of mobile phase on enantioseparation performance were investigated. For L-tryptophan, the retention factor (k’) increased significantly as the pH value increased from 5.0 to 7.0. While for D-tryptophan k’ rarely changed and the resolution factor (R-s) increased from 1.15 to 8.91. In contrast, the retention factor (k’) for RS- and SR-pidotimod decreased as the pH value increased from 5.0 to 7.0. For L-ben, k’ was only a slight increase when the pH value increased. The retention factors of three enantiomers fluctuated as ionic strength increased. However, Rs decreased when a buffer concentration increased.
