✦ Synopsis

Abstract

An efficient synthesis of 1,2,3,4‐tetrahydro‐2‐pyrimidinones and ‐thiones using ferric perchlorate as the catalyst from an aldehyde, ethyl acetoacetate, and urea or thiourea in acetonitrile was described. Compared to the classical Biginelli reaction conditions, this new method consistently has the advantage of full catalysis, good yields and short reaction time.
