Access to Divergent Benzo-Heterocycles via a Catalyst-Dependent Strategy in the Controllable Cyclization of o-Alkynyl-N-methoxyl-benzamides

Abstract

A chemo- and regio- selectively controllable approach for construction of diverse benzo-heterocycles is established. A new strategy of utility of ligand effect in gold catalysis to control the regioselectivity in the cyclization of o-alkynylbenzamides is successfully achieved. Meanwhile, chemoselectivity between nitrogen and oxygen nucleophiles is precisely switched by gold and platinum catalysts.
