                                    Humicola lanuginosa lipase-catalyzed acylation of beta -hydroxy sulfides provides both the (R)- and (S)-enantiomers in high enantiomeric purity. In two cases the resolved hydroxy sulfides were oxidized to give beta -hydroxy sulfoxides in > 99% e.e. The effect of substituents on enantioselectivity is discussed. (C) 2001 Elsevier Science Ltd.
