2,5,6,7,8-Pentasubstituted (S)- and (R)-[2-chroman-2-yl]ethanols as intermediates for the synthesis of α-tocopherol and its chiral analogs

In the presence of lipase from the yeast Candida cylindracea, partial acetylation of (±)-2-[6-benzyloxy-2,5,7,8-tetramethylchroman-2-yl]ethanol with vinyl acetate gives S-(+)-acetate whose alkaline hydrolysis affords (5)-( - )-alcohol. Repeated enzymatic
