An efficient tandem oxidative annulation for the synthesis of 2,2-disubstituted 2,3-dihydroquinazolin-4(1H)-ones via DDQ-mediated dual cross-dehydrogenative-coupling (CDC) reactions is described, resulting in moderate to excellent yields of the corresponding products.
An efficient tandem oxidative annulation for the synthesis of 2,2-disubstituted 2,3-dihydroquinazolin-4(1H)-ones via DDQ-mediated dual cross-dehydrogenative-coupling (CDC) reactions is described. This transformation proceeds from easily available o-aminobenzamides and 1,3-diarylpropenes under mild conditions, and the corresponding products are obtained in moderate to excellent yields.
