An efficient and practical procedure for the preparation of 2-substituted and 2,3-disubstituted quinazolinones was achieved through copper-catalyzed tandem reaction of 2-bromobenzamides with aldehydes and aqueous ammonia under air. Control experimental results indicated that this tandem reaction is triggered by a copper-catalyzed direct amination of 2-bromobenzamides with aqueous ammonia, followed by cyclocondensation and oxidative aromatization. As an application, this novel methodology provides a concise and practical one-pot route to the synthesis of alkaloid tryptanthrin. This journal is
Efficient one-pot synthesis of 2,3-dihydroquinazolin-4(1H)-ones from aromatic aldehydes and their one-pot oxidation to quinazolin-4(3H)-ones catalyzed by Bi(NO3)3·5H2O: Investigating the role of the catalyst
