The chemical synthesis of C-13-labeled D-galactose as useful molecular probes for studying the conformation of oligosaccharides attached to proteins was performed. The method for synthesizing the title labeled compounds was newly developed via the corresponding 1-ene and 5-ene compounds derived from 1,2:5,6-di-O-isoproppylidene-alpha-D-galactofuranose by considering the efficient introduction of the atom. All protons of galactose from H-1 to H-6 were observed by the HMQC-HOHAHA technique using 1:1 mixtures of methyl [1-C-13]- and [6-C-13]-beta-D-galactopyranoside, which were prepared from the title compounds.
