Recent advance in the synthesis of 3, 4-dihydropyrimidinones

The Biginelli reaction, which was first reported more than a century ago, involves the synthesis of 3,4 dihydropyrimidin 2(1 H ) ones of type 4 by a very simple one pot condensation reaction of ethyl acetoacetate, benzaldehyde and urea in ethanol. In the past decade, dihydropyrimidine derivatives have exhibited important pharmacological properties, e.g. as the integral backbones of several calcium channel blockers, antihypertensive agents, alpha 1a antagonists, and neuropeptide Y (NPY) antagonists. In this article, we review development in the Biginelli reaction in the areas such as catalytic synthesis, solid phase synthesis, microwave irradiation, mechanism and natural products synthesis.
