The efficiency of various heteropoly compounds as well-known solid acids is investigated for the three-component condensation reaction of an aldehyde, b-ketoester and urea to afford the dihydropyrimidinones (DHPM). Compared to the classical Biginelli

International audience; Phenylboronic acid was shown to mediate the free-radical multicomponent carbo-cyanation of olefins and the addition of alkyl iodides onto vinylsulfones. Reaction of the boronic acid with di-tert-butyl hyponitrite generates an
