Synthesis of a glucoheptaose - The repeating unit of lentinan

An allyl glucoheptaoside, allyl β-D-Glu-(1→3)-[β-D-Glu-(1 →6)]-β-D-Glu-(1→3)-β-D-Glu-(1→3)-[β-D-Glu-(1→6)]-β-D-Glu-(1→3)-β-D- Glucoside, representing the repeating unit of lentinan was synthesized through a stepwise way. The key step involved di-6-O-selective glycosylation using perbenzoylated glucopyranosyl imidate as the donor and 1→3-β-linked pentasaccharide having 4,6-free hydroxy groups at B and D rings as the acceptor.
