syn-α,β-Dihydroxy thioesters are prepared in good yields with high diastereo- and enantioselectivities by the asymmetric aldol reaction of 1-trimethylsiloxy-1-ethylthio-2-t-butyldimethylsiloxyethene with aldehydes using a chiral promoter consisting of tin(II) triflate, a chiral diamine and dibutyltin diacetate.
