A catalytic regio- and stereoselective 1,4-hydroboration of 1,3-dienes was accomplished with pinacolborane in the presence of Ni(cod)2and PCy3. This reaction exhibits broad substrate scope operating on a range of substituted dienes and occurs with generally high levels of selectivity and efficiency. Reactivity patterns suggest that the reactive conformation of the diene is theS-cis form. The intermediate allylboronate can be oxidized to stereodefined allylic alcohols or can be used in stereoselective carbonyl addition reactions.
