摘要：

This paper describes our recent study of glycosyl phosphites for glycosylation reactions, with particular emphasis on the investigation of protecting group and stereochemistry effects on the anomeric reactivity and stereoselectivity, and the application of this methodology to the synthesis of Lewis X (Le(x)), Lewis Y (Les(y)), glycopeptides, and sialyl Lewis X (SLe(x)) mimetics. Bath alpha-O-fucosyl-L-threonine and alpha-O-fucosyl-(1R,2R)-2-aminocyclohexanol were found to be effective templates for the chemical/enzymatic synthesis of SLe(x) mimetics, and some-fucopeptides prepared were 5-10 times more active than SLe(x) as inhibitors of E-selectin.
