Micro wave-Assisted Synthesis of Amides from Various Amines and Benzoyl Chloride under Solvent-Free Conditions: A Rapid and Efficient Method for Selective Protection of Diverse Amines

摘要

A number of structurally diverse amides were synthesized by reaction of the corresponding amines with benzoyl chloride under microwave irradiation. The proposed procedure ensures short reaction time, high yields, and excellent selectivity and considerably broadens the series of amines as compared to the microwave-assisted synthesis of amides directly from carboxylic acids. It can also be used for selective protection of various amines, including aromatic, aliphatic, and heterocyclic.
