A highly efficient regio- and stereoselective method for allenoate borylation has been developed. Using CuCl and bis(pinacolato)diboron in methanol, a variety of allenoates underwent β-boration and α-protonation to afford the corresponding Z-β,γ-unsaturated β-boryl esters under mild conditions with up to 81% yields.

A mild and efficient copper-catalyzed borylation of electron deficient allenoates using an sp2-sp3 mixed hybridized diboron regioselectively installs a boron moiety on the β-position with exclusive (Z)-double bond geometry.
