A facile synthesis of the tetrasaccharide repeating unit of mannoglucan from Microellobosporia grisea

A facile synthesis of the tetrasaccharide repeating unit of mannoglucan from Microellobosporia grisea was achieved through coupling of 4,6-O-benzylidene-1,2-O-ethylidene-α-D-glucopyranose with per-O-benzoylated mannopyranosyl trichloroacetimidate, followed by debenzylidenation, selective 6-O-mannopyranosylation, then hydrolysis of the 1,2-O-ethylidene group, 1,2-O-acetylation and conversion to the 1-trichloroacetimidate, and subsequent condensation of the activated trisaccharide with allyl 2,3,6-tri-O-benzoyl-α-D-glucopyranoside.
