Abstract
A copper-catalyzed one-pot synthesis of 2,3-dihydroquinazolin-4(1H)-ones with diboronic acid as a reductant in an aqueous medium is described. Various 2,3-dihydroquinazolin-4(1H)-ones were prepared with good functional-group tolerance in good yields under mild conditions from readily available 2-nitrobenzonitriles and various carbonyl compounds.
