A stereoselective α-fucosylation reaction using 1-hydroxy donor for the practical synthesis of selectin blocker
摘要:
A l-hydroxy 2,3,4-tri-O-benzyl-L-fucose donor affords a high stereoselectivity of glycosylation in the presence of TMSOTf and is a very useful substrate for the preparation of an alpha-L-fucosyl dipeptide in a stereoselective manner. The donor will be a key component in the preparation of an attractively biological selectin blocker 1. (C) 1998 Elsevier Science Ltd. All rights reserved.
