Copper-catalyzed efficient synthesis of 5-arylindazolo[3,2-b]quinazolin-7(5H)-ones from 2-nitrobenzaldehydes

A novel and practical copper-catalyzed approach was developed for the preparation of 5-arylindazolo[3,2-b]quinazolin-7(5H)-ones. The 2-amino-N′-arylbenzohydrazideis easily prepared by a reaction of isatoic anhydride with arylhydrazine. Then, through a con

Copper(I)-catalyzed synthesis of 5-arylindazolo[3,2- b ]quinazolin-7(5 H)-one via ullmann-type reaction

The treatment of 2-amino-N′-arylbenzohydrazide and o-halogenated benzaldehyde in the presence of CuBr and Cs2CO3 gave 5-arylindazolo[3,2-b]quinazolin-7(5H)-one in high yields. This procedure contains an Ullmann-type reaction and prov
