The synthesis of polysaccharides containing oligosaccharide repeating units has been accomplished by polycondensation of suitable monomers, namely, trityl ethers of 1,2-0(1-cyanoethylidene) derivatives of the respective oligosaccharides'-3. These monomers were prepared from 1,2-0-(1-cyanoethylidene)

The condensation of acetylated I-(endo-cyano)ethylidene derivatives having the D-&TO, D-xylo, and D-@&CtO configurations (2-6) with a primary (8) and a secondary (9) trityl derivative was more rapid than for the corresponding exoisomers. This difference in reactivity is explained on the basis of di
