An enantioselective total synthesis of the stilbenolignan (-)-aiphanol and the determination of its absolute stereochemistry

The title natural product (-)-aiphanol has been prepared by total synthesis. A key step involved the asymmetric dihydroxylation of (E)-3,5-dimethoxy-4-(methoxymethoxy)cinnamyl alcohol with the AD-mix-β to give triol (1R,2R)-1-(3′,5′-dimethoxy-4′-methoxymethoxyphenyl) -2,3-dihydroxypropanol, the absolute stereochemistry of which was confirmed by single-crystal X-ray analysis of a readily available bromo-derivative. These studies have established that the naturally occurring enantiomer of aiphanol possesses the (S)-configuration at each of C-2′ and C-3′.
