Triphenylphosphinedibromide and dimethylsulfide dibromide are efficient reagents for the direct synthesis of beta-lactams from carboxylic acids and imines avoiding the use of acid halides as starting materials. Synthesis of 4-imino-beta-lactams are also briefly described. A potential synthesis of N-unsubstituted beta-lactams is made.
