Abstract

Abstract A new, facile, and efficient one-pot deprotection–cyclocondensation method is presented for the Biginelli reaction from aryl acylals or aryl aldehyde bisulfites in the presence of catalytic amounts of Bi (NO 3) 3⋅ 5H 2 O under solvent-free conditions. In addition, high levels of chemoselectivity for this synthesis have been achieved.© 2007 Wiley Periodicals, Inc. Heteroatom Chem 18: 684–687, 2007; Published online in Wiley ...
