  描述：

  (1R,2R)-2,3-epoxy-1-(3',5'-dimethoxy-4'-methoxymethoxyphenyl)propanol 在 palladium on activated charcoal 偶氮二甲酸二异丙酯 、 氢气 、 三苯基膦 作用下， 以 四氢呋喃 、 乙酸乙酯 、 甲苯 为溶剂， 反应 33.0h， 生成 (1'S,2'R)-4-hydroxy-3-[2',3'-epoxy-1'-(3'',5''-dimethoxy-4''-methoxymethoxyphenyl)-propoxy]-benzaldehyde

  名称：

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

  摘要：

  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-beta 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'. (C) 2005 Elsevier Ltd. All rights reserved.
