Biginelli reaction: an overview

Tetrahedron Letters, 2016
Abstract Biginelli reaction involves acid-catalyzed one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) using easily-accessible starting materials, namely, aldehyde, active methylene compound and (thio)urea. DHPMs have stimulated resurgence of interest in the past two decades due to their wide ranging pharmacological activities and presence ...

The Biginelli Reaction

Journal of Chemical Education, 2001
The utilization of the Biginelli reaction, a one-pot condensation of an aldehyde, a β-keto ester, and urea, is described. This reaction involves a number of individual steps, each of which is accessible to first-year organic students. The product, a 3,4-dihydropyrimidinone, is a member of a medicinally useful class of compounds.
