Copper(I)-Catalyzed Synthesis of 5-Arylindazolo[3,2-b]quinazolin-7(5H)-one via Ullmann-Type Reaction
摘要:
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 provides an efficient method to construct fused tetracyclic heterocycles.
