N -(2-Aminobenzoyl)benzotriazole Mediated Synthesis of 3-Acyl-2-alkyl(aryl)-4-hydroxyquinolines and 3-Acylamino-4(3 H ) quinazolinones.

New methods have been developed for the synthesis of the substituted quinolines and quinazolinones derivatives by utilizing N -(2-aminobenzoyl)benzotriazoles under mild reaction conditions. 3-Acyl-2-alkyl(aryl)-4-hydroxyquinolines were obtained in modarete yields by the reaction of N -(2-aminobenzoyl)benzotriazoles and diketones in the presence of tert -BuOK. 3-Acylamino-4(3 H ) quinazolinones were obtained in good yields via N -(2-aminobenzoyl)benzotriazoles, orthoester and hyrazides in one-pot.
