An asymmetric addition of vinyl group to ketones using vinylaluminum reagents catalyzed by in situ prepared Ti(OiPr)4 complexes of (S)-BINOL affords diversified tertiary allylic alochols. Various aromatic ketones can be converted to allylic alcohols in excellent enantioselectivities with high yields.
