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.
