Abstract

A Pd-catalyzed direct borylation of various 1,1- and 1,2-disubstituted alkenes provides trisubstituted alkenyl boronic esters with outstanding yields and excellent E/Z selectivities via a boryl-Heck pathway. Several derivatizations of the alkenyl boronic esters allow access to diverse, stereodefined, functionalized olefins.
