Enantiomerically pure )-(1R)-tricarbonyl-(2-methoxybenzaldehyde)chromi
um reacts with 2-mercaptobenzylalcohol to give the corresponding diast
ereomeric thioacetal complexes, which are separated and transformed qu
antitatively into the enantiomerically pure thioacetals (+)- and (-)-5
by removing the chromium tricarbonyl moiety. Copyright (C) 1996 Publi
