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.

Recent progress in asymmetric Biginelli reaction

Molecular Diversity, 2013
The Biginelli reaction, which involves the interaction of ethyl acetoacetate, urea, and an appropriate aryl aldehyde, was first discovered by Pietro Biginelli about 120 years ago. The Biginelli products (3,4-dihydropyrimidin-2(1H)-ones) are interesting materials due to their significant pharmacological and structural profiles.

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 ...

Tandem Hydroformylation-Biginelli Reaction

Synlett, 2013
The combination of a tandem process with a multicomponent reaction is a new approach to high atom-economic synthesis. A tandem hydroformylation–Biginelli reaction sequence has been developed leading to a variety of functionalized 4-alkyl-substituted 3,4-dihydropyrimidin-2(1H)-ones.
