Abstract
(-)-Desoxoprosopinine was synthesised from (R)-phenylglycinol as the c hiral source. The three distinct steps used for the construction of th e three stereogenic centers of the target were all highly diastereosel ective. These steps include a reduction of a homochiral N-Boc-2-acyl o xazolidine and the stereoselectivity of this reaction can be explained by a non chelated model. An original N-debenzylation of the phenyl gl ycinol appendage was devised in this synthesis. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
