Abstract

An efficient copper-catalyzed cascade reaction of (2-aminophenyl)methanols with aldehydes using the combination of cerium nitrate hexahydrate and ammonium chloride leads to a wide range of 2-substituted quinazolines in good yields. The method tolerates a various functional groups and represents a convenient and practical strategy for synthesis of 2-substituted quinazoline derivatives.
