An array of enantioenriched vinyl boronates bearing an allylic carbonate moiety have been
prepared through selective hydroboration of propargyl carbonates. Treatment of these vinyl boronates
with TBAF in THF affords enantioenriched 1,3-
disubstituted allenes through a novel 1,2-anti elimination in good yields and high enantiospecificitiesWe thank MINECO (CTQ2016-78779-R) and MICINN
