Golden Cascade: With a tethered, electron‐rich arene as the internal nucleophile, a gold‐catalyzed amide cyclization to an alkyne initiates a cascade process that ends with a Ferrier rearrangement. Electron‐rich arene‐bearing hexahydroquinolizin‐2‐ones are formed in good yields and can be converted into indole alkaloids in only a few steps.
黄金级联:以束缚的、富电子的芳烃作为内部亲核试剂,金催化的酰胺环化成炔引发级联过程,以费里尔重排结束。富含电子的芳烃六氢喹啉-2-酮以良好的产率形成,只需几步即可转化为吲哚生物碱。
