N,N-DIMETHYLPHOSPHORAMIDIC DICHLORIDE: A CONVENIENT REAGENT FOR THE PREPARATION OF β-LACTAMS FROM ACETIC ACIDS AND IMINES

A convenient reagent for the preparation of β-lactams from acetic acids and imines is described.A new route to α-keto-β-lactams from 3-bis(ethylthio)β-lactams is also reported.Reaction of 4-acethyl-β-lactams with diazomethane is also made.

A CONVENIENT SYNTHESIS OF AZETIDINE-2,3-DIONES (α-Keto-β-Lactams)

Azetidine-2,3-diones can be conveniently synthesized by mild hydrolisis of the product of the reaction between α-phenylthio-β-lactams and sulfuryl chloride.
