Abstract

α-d-Mannosylphosphate serine derivatives were conveniently synthesized by reaction of benzyl or cyanoethyl phosphochloroamidites with 2,3,4,6-tetra-O-acetyl-d-mannose to give intermediate α-mannosyl phosphoramidites, which were successfully reacted with properly protected serine derivatives in the presence of 1H-tetrazole to give phosphite triesters which could be oxidized to phosphotriesters using t-BuOOH.
