Catalytic asymmetric aldol reaction of the silyl enol ether derived from S-ethyl ethanethioate with achiral aldehydes is carried out by using chiral diamine-coordinated tin(II) triflate to afford the corresponding aldol-type adducts, alpha-unsubstituted beta-hydroxy thioesters, in good yields with high ees.
