R. Thangarasa et al., DIASTEREOSELECTIVITY IN CHIRAL (ARENE)TRICARBONYLCHROMIUM HOMOBENZYLIC ALCOHOL COMPLEXES - ASYMMETRIC-SYNTHESIS OF DIHYDROISOCOUMARINS, Journal of the Chemical Society, Chemical Communications, (4), 1994, pp. 501-502
Enantiomerically pure (arene)tricarbonylchromium complexes of homobenz
ylic ketones 3 undergo stereoselective reduction to give the correspon
ding alcohols, which may be transformed readily into enantiomerically
pure dihydroisocoumarins.
