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.

Aminoheterocycles as synthons for combinatorial Biginelli reactions

Molecular Diversity, 2010
Chlorotrimethylsilane (TMSCl) has been utilized as an efficient promoter and water scavenger in the synthesis of diverse dihydropyrimidines via Biginelli type MCR-heterocyclization using aminoheterocycles. High yields and a simple workup of target compounds enable the facile generation of combinatorial libraries comprising more than 2,000 compounds of ...
