title: Synthesis of trisubstituted alkenylstannanes through copper-catalyzed three-component coupling of alkylboranes, alkynoates, and tributyltin methoxide.
abstract: A versatile route to trisubstituted alkenylstannanes is presented. The alkyl and Sn moieties were introduced at the β and α carbon atoms of alkynoates, respectively, in a formal syn addition mode with complete regioselectivity. A variety of functional groups were tolerated in the alkylboranes and alkynoates.
