ASYMMETRIC ALLYLATION OF PROCHIRAL ALDEHYDES WITH A NEW ENANTIOSELECTIVE ALLYLATING AGENT PREPARED FROM STANNOUS TRIFLATE, A CHIRAL DIAMINE, AND ALLYLDIALKYLALUMINUM
A new enantioselective allylating agent, prepared by treatment of a mixture of stannous trifluoromethanesulfonate and a chiral diamine with allyldialkylaluminum, reacts with prochiral aldehydes to give secondaryhomoallylalcohols in good optical yield.
