A chiral allylating agent, readily generated from tin(II) trifluoromethanesulfonate (tin(II) triflate), chiral diamines derived from (S)-proline and allylaluminum, is efficiently employed in the asymmetric allylation of aldehydes and an epoxide. Reaction of a chiral 2-methyl-2-propenylating (methallylating) agent with aldehydes also proceeds smoothly to afford the corresponding homoallylic alcohols
