An unprecedented and efficient domino reaction of diphenyl vinyl sulfonium salt with carbamates leading to the syntheses of N-aryloxazolidin-2-ones has been developed. The scope of this transformation has been studied and a plausible mechanism has been proposed.
A one-step procedure for efficient synthesis of oxazolidinone only using ethylene carbonate and arylamines in the presence of 1,4-diazabicyclo[2,2,2]octane (DABCO) was developed. In most cases, moderate to high yield of products were obtained. This reaction can be considered a carbon dioxide fixation reaction since ethylene carbonate was synthesized via reaction of ethylene oxide with carbon dioxide.
CuSO4-mediated decarboxylative C-N cross-coupling of aromatic carboxylic acid with amide has been developed, leading to N-arylamides in modest to excellent yields. Anilines bearing electron-withdrawing substituents could also couple efficiently with aromatic carboxylic acids to give diarylamines in good to excellent yields. (C) 2014 Published by Elsevier Ltd.

CuI/N,N-dimethylglycine catalyzed coupling of aryl bromides with substituted oxazolidinones took place at 120 degrees C in DMF, affording the corresponding N-arylation products with good to excellent yields. A number of functional groups, such as ketone, nitrile, nitro, methoxy, and hydroxyl were tolerated under these conditions, thereby allowing diversity synthesis of N-aryloxazolidinones.
