Palladium (II)-catalyzed carbon–carbon bond formation between allyl 2, 3, 4, 6-tetra-O-acetyl- β-d-glucopyranoside () and arylboronic acid congeners gave the corresponding cinnamyl 2, 3, 4, 6-tetra-O-acetyl-β-d-glucopyranosides () in good yield. Among them, coupling products were converted to not only the naturally occurring phenylpropenoid β-d-glucopyranoside analogues () but also the unnaturally ones ().
