摘要
A copper-catalyzed aerobic oxidative ring expansion reaction of isatins with 1,2,3,4-tetrahydroisoquinoline for the synthesis of tetra-cyclic quinazolinones has been developed.This reaction is performed smoothly under simple conditions to give the corresponding products in moderate to good yields with good functional group tolerance.
