Stereoselective synthesis of oxazolidines from 2-amino-2-deoxy-d-allose derivatives and their reactivity with nucleophiles
摘要:
The use of 2-amino-2-deoxy-D-allose in the synthesis of oxazolidines is described. The reaction takes place with total stereoselectivity in the preparation of both simple oxazolidines (from aldehydes as reagent) and bicyclic oxazolidines (from chlorocarbonyl compounds and keto-acids as reagents). The reactivity of the obtained oxazolidines with hydride and alkylmagnesium chlorides is also described. (C) 2001 Published by Elsevier Science Ltd. All rights reserved.
