Abstract
4-O-β-D-Galactopyranosyl-L-rhamnopyranose has been synthesized in 60% yield by condensation of 2,3,4,6-tetra-O-acetyl-α-D-galactopyranosyl bromide with methyl 2,3-O-isopropylidene-α-L-rhamnopyranoside using mercuric cyanide in acetonitrile (Helferich reaction). The disaccharide is a syrup but the derived alditol and alditol peracetate are crystalline compounds.Keywords
