Practical povidone iodine catalyzed transamidation from primary amides and amines

Abstract

Non-harmful Povidone iodine (PVP-I) was applied in the transamidation to gain N-substituted amides from various primary amides and amines. Diverse aromatic, heterocyclic and aliphatic primary amides/amines were applied in our developed method and more than 45 N-substituted amides were obtained with excellent yields in most cases. Several drugs such as Melatonin and Efaproxiral were successfully acquired with a better performance than those previous reported results.
