A catalytic diastereo- and enantioselective method for the preparation of complex tertiaryhomoallylicalcohols containing a vicinal quaternary carbon stereogeniccenter and a versatile alkenylboronic ester is disclosed. Transformations are promoted by 5 mol % of a readily available copper catalyst bearing a bulky monodentate phosphoramidite ligand, which is essential for attaining both high dr and
