Seven 4-aryl-5-isopropoxycarbonyl-6-methyl-3,4-dihydropyrimidin-2(1H)-ones 4a-g and 4-phenyl-5-isopropoxycarbonyl-6-methyl-3,4-dihydropyrimidin-2(1H)-thione 4h have been synthesized by a one-pot cyclocondensation of aldehydes, isopropyl acetoacetate and u
Calcium fluoride: an efficient and reusable catalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and their corresponding 2(1H)thione: an improved high yielding protocol for the Biginelli reaction

experimental part, p. 2222 - 2224 (2009/08/07)
A simple and effective synthesis of 3,4-dihydropyrimidinone derivatives from aldehydes, 1,3-dicarbonyl compounds, and urea/thiourea in ethanol by using calcium fluoride as catalyst has been described. Compared with classical Biginelli reaction conditions,
