Synthesis of 13 was achieved from 2,3,4,6-tetra-O-benzyl-α-D-galactopyranosyl chloride by the reaction with allylmagnesium bromide (0 °C), followed by ozonolysis and the reductive opening of the ozonide. For a similar series of reactions, see: Uchiyama, T.; Woltering, T. J.; Wong, W.; Lin, C.-C.; Kajimoto, T.; Takebayashi, M.; Weitz-Schmidt, G.; Asakura, T.; Noda, M.; Wong, C.-H. Bioorg. Med.
