Aldol 5b, easily obtained from dihydrocarvone 6b, reacts with organolithium
and Grignard reagents leading to enantiomerically enriched alcohols 8 (ee
up to 35%). Thus, aldol 5b is a synthetic equivalent of benzaldehyde with a
masked prochiral face. (C) 1999 Elsevier Science Ltd. All rights reserved.
