Abstract

Scalable syntheses of piceatannol-3′-O-β-d-glucopyranoside and the 4′-methoxy congener thereof were achieved. This route features an early implemented Fischer-like glycosylation reaction, a regioselective iodination of phenolic glycoside under strongly acidic conditions, a highly telescoped route to access the styrene derivative, and a key Mizoroki–Heck reaction to render the desired coupled products in high overall yield.
