AN EFFICIENT TRANSFORMATION OF N-ACYL-α-AMINO ACIDS INTO DIACYLAMINES VIA 2, 4-DISUBSTITUTED OXAZOL-5 (4H)-ONES

Abstract

Base-catalyzed oxygenative decarboxylation of a variety of 2, 4-disubstituted oxazol-5 (4H)-ones in benzene with triethylamine or in dimethyl sulfoxide with potassium tert-butoxide gives diacylamines.
