THE EFFECT OF HIGH PRESSURE ON THE STEREOSPECIFICITY OF THE GLYCOSYLATION REACTION

At a pressure of 1,4 GPa and room temperature, the glycosylation of trityl ethers by 1,2-O-cyanoethylidene derivatives of sugars, and the polycondensation of the proper monomers in dichloromethane, proceed with absolute stereospecificity, giving rise to a

SYNTHESIS OF POLYSACCHARIDE Α-(1-3)-L-RHAMNAN

The regular polysaccharide α-(1-3)-L-rhamnan (DP ca. 30) was obtained by polycondensation of 4-O-acetyl-3-O-trityl-1,2-O-exo-cyanoethylidene-L-rhamnopyranose catalysed with triphenylmethylium perchlorate.
