Synthetic conversion of cellobiose into the glycal-type monomers and their polymerization

A pair of disaccharidic glycals thoroughly O-benzylated except the 4'- or the 6'-hydroxyl groups were prepared as the monomers for iodonium ion- promoted polymerization, which proceeded under dark conditions to give polysaccharides of more than DP 12 (24 saccharide). Reductive removal of the iodine atom and subsequent deprotection gave polysaccharides alternatively composed of β-D-glucopyranosyl and 2-deoxy-α,β-D-glucopyranosyl residues.

HYDROGENOLYSIS OF THE BENZYLIDENE ACETALS OF THIOGLYCOSIDES WITH THE LiAlH4-AlCl3 REAGENT. SYNTHESIS OF PARTIALLY BENZYLATED THIOGLYCOSIDE DERIVATIVES

Reductive hydrogenolysis of phenyl 2,3-di-O-benzyl-4,6-O-benzylidene-1-thio-β-D-gluco- (4) and -galactopyranoside (8) and phenyl 2,3,6,2',3'-penta-O-benzyl-4',6'-O-benzylidene-1-thio-β-cellobioside (15) with the LiAlH4-AlCl3 reagent resulted in the corres
