Abstract

Reaction of aldehydes with methallyltributyltin or crotyltributyltin in the presence of a catalytic amount of BINAP×silver(I) complex affords the corresponding optically active homoallylic alcohols with high enantioselectivities; γ- and antiselectivities are also obtained for crotyltributyltin.

Key words

catalytic enantioselective allylation - BINAP×silver(I) complex - methallyltributyltin - crotyltributyltin - aldehyde
