Abstract
An efficient synthesis of 3,4-dihydropyrimidinones using lanthanum chloride heptahydrate as a catalyst from an aldehyde, β-keto ester and urea or thiourea in ethanol is described. Compared to the classical Biginelli reaction conditions, this new method consistently has the advantage of good yields (56–97%).
