An asymmetric allylation of aldehydes with the allyltin tribromide was achieved using the l-prolinederivative as a chiral promoter in dichloromethane in the presence of a Lewis base. Various optically active homoallylic alcohols were obtained in high yields with moderate enatioselectivities of up to 62% ee.
