Direct enantiomeric separation of racemic mixtures of 13 β-amino alcohols and β-hydroxy sulfides was achieved by HPLC using Chiralcel OD, Chiralcel OJ and Chiralpak AD as chiral stationary phases and hexane/2-propanol mixture as eluent. These racemates were completely separated into enantiomers at least on one of these stationary phases.
