摘要：The development of a novel ( Z)-α,δ-bisboryl-substituted crotylboron reagent is reported. Ni-catalyzed 1,4-diboration of dienylboronate provided the targeted crotylboronate in good yield with high regio- and stereolectivity. Chemo- and stereolective addition of this crotylboron reagent to aldehydes followed by protection of the resulting condary hydroxyl group gave TES-protected homoallylic alcohols bearing an alkyl and a vinyl boronate groups with high stereolectivities.
