✦ Synopsis

Abstract

A series of Biginelli compounds was synthesized using TsOH as a catalyst under microwave irradiation. This simple method provided the title compounds in 86%–98% yields by the reaction of aromatic aldehydes with 1,3‐carbonyl compound and urea. The structure of 4o was determined by single crystal X‐ray diffraction analysis.
