Abstract

By hydrosilylation of 1-O-allyl-2,3,4,6-tetra-O-acetyl-β-D-glucopyranose and 1-O-allyl-2,3,4,6-tetra-O-acetyl-β-D-galactopyranose with 1,3-bis(dimethylsilyl)-2,2,4,4-tetramethylcyclodisilazane in the presence of the catalyst Co2(CO)8, we have obtained 1,3-di[3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)propyldimethylsilyl]-2,2,4,4-tetramethylcyclodisilazane and 1,3-di[3-(2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyloxy)propyldimethylsilyl]-2,2,4,4-tetramethylcyclodisilazane. By deacetylation, we obtained 1,3-di[3-(β-D-glucopyranosyloxy)propyldimethylsilyl]-2,2,4,4-tetramethylcyclodisilazane.
