A concise synthetic approach to the marine natural product (+)-aureol has been achieved from readily available starting materials using obviously fewer steps in comparison to the related report in literature (6 steps versus 12 steps from (+)-sclareolide). Key steps of this protocol include a boron trifluoride-catalyzed domino 1,2-H and 1,2-methyl shifts and a nickel(II)-catalyzed cross-coupling reaction
与文献中的相关报道相比,由现成的起始原料使用明显更少的步骤就可以实现一种简单的合成海洋天然产物(+)-aureol的方法(从(+)-紫杉醇中提取6步,而在12步中)。该协议的关键步骤包括三氟化硼催化的多米诺骨牌1,2-H和1,2-甲基转移以及镍(II)催化的烷基碘与芳基格氏试剂之间的交叉偶联反应。
