A chemo- and regio-selectively controllable approach for construction of diverse benzo-heterocycles is established. A new strategy for using the ligand effect in gold catalysis to control the regioselectivity in the cyclization of o -alkynyl- N -methoxyl-benzamide is successfully achieved. Meanwhile...

description A chemo- and regio-selectively controllable approach for construction of diverse benzo-heterocycles is established. A new strategy for using the ligand effect in gold catalysis to control the regioselectivity in the cyclization of o -alkynyl- N -methoxyl-benzamide is successfully achieved. Meanwhile, the chemoselectivity between nitrogen and oxygen nucleophiles is precisely switched by gold and platinum catalysts. A chemo- and regio-selectively controllable approach for construction of diverse benzo-heterocycles is established. The ligand controls the regioselectivity and the metal dominates the chemoselectivity.
