Abstract

Enantioenriched carbanionic pairs generated by the asymmetric deprotonation of carbamate eaters with the chiral base s-butyllithium/(-)-sparteine undergo smoothly intramolecular conjugate addition reactions to dienes and enynes in high yields. (C) 1999 Elsevier Science Ltd. All rights reserved.
