Abstract
Enantiomerically pure (-)-(1R)-tricarbonyl-(2-methoxybenzaldehyde)chromium reacts with 2-mercaptobenzylalcohol to give the corresponding diastereomeric thioacetal complexes, which are separated and transformed quantitatively into the enantiomerically pure thioacetals (+)- and (-)-5 by removing the chromium tricarbonyl moiety.
