Abstract

Abstract A one step synthesis of 1, 4-benzodiazepines from o-haloanilines and amino acids was achieved by use of palladium catalyzed carbonylation, by which application a synthesis of the model compounds (23a and 23b) of Neothramycin (A and B) was described. An efficient chemoselective reduction of the amide was provided.
