Abstract

Addition of 1-pentadecenylzirconocene chloride to 2,3-O-cyclohexylidene-(R)-glyceraldehyde in CH2Cl2 was best promoted by trimethylsilyl triflate (TMSOTf) to give the diastereomeric anti- and syn-alcohols in 80% yield. TMSOTf also showed remarkable catalytic activity for the addition of 1(E)-alkenylzirconocenes to ketones, giving tertiary allylic alcohols in good yields.
