An efficient Cu-catalyzed cyclization of N-propargyl ynamides with borane adducts through B-H bond insertion was developed. Valuable organoboron compounds are constructed in generally good yields with a wide substrate scope and good functional group tolerance under mild reaction conditions. Importantly, this protocol via vinyl cation intermediates constitutes a novel way of B-H bond insertion.
