Answer
![Methyl (2S,3R,4S)-2-(beta-D-glucopyranosyloxy)-4-{2-[(3,4,5-trihydroxybenzoyl)oxy]ethyl}-3-vinyl-3,4-dihydro-2H-pyran-5-carboxylate](https://static.chemtradehub.com/structs/131/131189-57-6-0085.webp "Methyl (2S,3R,4S)-2-(beta-D-glucopyranosyloxy)-4-{2-[(3,4,5-trihydroxybenzoyl)oxy]ethyl}-3-vinyl-3,4-dihydro-2H-pyran-5-carboxylate")
The compound is typically synthesized via a multi-step approach involving condensation of glucopyranosyl chloride with a vinyl ester, followed by hydroxylation and benzoylation. The use of Lewis acids like aluminium trichloride and catalytic amounts of base is common in the synthesis, providing high yield and good selectivity.
