The title pentasaccharide was synthesized via a 2 + 3 strategy. The disaccharide donor, 3-O-acetyl-2-O-benzoyl-4,6-O-benzylidene-β-d- glucopyranosyl-(1→3)-2-O-benzoyl-4,6-O-benzylidene-α-d- glucopyranosyl trichloroacetimidate (8), was obtained by selectiv
Regioselective benzoylation of 6-O-protected and 4,6-O-diprotected hexopyranosides as promoted by chiral and achiral ditertiary 1,2-diamines

Monobenzoylation of triols (6-O-silylated glycopyranosides) or diols (4,6-O-benzylidenated glycopyranosides) with benzoyl chloride and triethylamine at - 60° to 23° is promoted by catalytic amounts of ditertiary 1,2-diamines. The regioselectivity depends
