Abstract
A new route towards the asymmetric preparation of alpha -substituted propyn ylamines has been developed. The key step involved a diastereoselective add ition of diethylalkynylaluminum to oxazolidines derived from R-(-)-phenylgl ycinol. The use of this reaction for the rapid preparation of a polysubstit uted isoindoline framework is described. (C) 2001 Elsevier Science Ltd. All rights reserved.
