title: Borylstannylation of alkynes with inverse regioselectivity: copper-catalyzed three-component coupling using a masked diboron.
abstract: A variety of terminal alkynes are facilely convertible into cis-boryl(stannyl)alkenes with inverse regioselectivity to those of the previous borylstannylation by the copper-catalyzed three-component reaction using a masked diboron. The synthetic utility of the resulting boryl(stannyl)alkenes has been demonstrated by chemoselective coupling reactions.
