摘要：
3-0-Acetyl- and 28-0-acetyl-betulin were mannosylated with tetra-0-benzoyl-alpha-D-mannopyranosyl trichloroacetimidate. Debenzoylation of the monosaccharide obtained followed by treatment with 2 equiv of tetra-0-benzoyl-alpha-D-mannopyranosyl trichloroacetimidate selectively gave 0-3,0-6-linked trimannosides.
