Convenient Synthesis of 5-Arylidene-2-imino-4-thiazolidinone Derivatives Using Microwave Irradiation

摘要

A concise approach for the preparation of 5-arylidene-2-imino-4-thiazolidinone derivatives is described. Structurally diverse amines, isothiocyanates, aldehydes, and chloroacetyl chloride were combined under microwave irradiation to afford new 5-arylidene-2-imino-4-thiazolidinone derivatives. The one-pot synthesis involves the in situ formation of a thiourea followed by reaction with chloroacetyl chloride and an aldehyde to generate the target compounds.
