Abstract
NEW MATERIAL:Benzylated saccharide derivatives of the formula (Bn is benzyl).
EXAMPLE: Methyl 3,6-di-O-allyl-α-D-mannopyranoside.
USE: Synthetic intermediate of branched oligosaccharides, food additive as a sugar ester, synthetic intermediate of various kinds of antibiotics and macrolide compounds.
PREPARATION: Methyl α-D-mannopyranoside, methyl β-D-galactopyranoside and bis(trialkyltin) oxide are made to react in an aprotic solvent such as toluene to form an alkyltin compound, which is made to react with an allylating agent such as allyl chloride to give an allylated saccharide derivative. Susequently, a benzylating agent such as benzyl bromide is made to act and the allyl group is removed to give the compound of the formula.
