isolated from the maycelia of Epidermophyton floccosum . Methylation, periodate oxidation, and acetolysis studies suggested that S-lawe is composed of (1→6)- O α- d -mannopyranosyl-(1→6)- O -[α- d -mannopyranosyl-(1→2)]- O -α- d -mannopyranosyl repeating units. Condensation of 2,3,4,6-tetra- O -acetyl-α- d -mannopyranosyl bromide with methyl 3- O -benzyl-4,6- O -benzylidene-α- d -mannopyranoside in
