Abstract
The stereoselective base-catalyzed addition of (R)-pantolactone to the ketene derived from racemic N-phthalyl valine is reported. The R or S configuration of the newly generated asymmetric centre of the pantola ctonyl ester is highly dependent on the tertiary amine catalyst employ ed. (C) 1997 Elsevier Science Ltd.
