2-O-Acetylation of 2-(4-allyloxyphenyl) ethyl 4,6-O-benzylidene- β-D-glucopyranoside (1) gave 2, which reacted with triacetylrhamnopyranosyl bromide to yield 3. Protective Osmanthuside B~6 (5) was synthesized by reaction of p-acetyloxycinnamoyl chloride and 4 at low temperature, which was obtained by removing benzylidene of 3. Selective acetylation of 4 gave 6. Compound 6 reacted with p-acetyloxycinnamoyl chloride and 3,4-di-O-allylcaffeic acid respectively to afford two corresponding protective disaccharide phenylpropanoid glycosides, 7 and 8.
