unprotected, N-alkyl and N-aryl 3-cyanoindoles are obtained with good to excellent yields. The usefulness of this synthetic approach is further demonstrated by the successful synthesis of practical compounds such as the therapeutic estrogen receptor ligand A precursor. Mechanism study shows that the tandem catalysis exploits a Suzuki cross-coupling with subsequent base-induced isoxazole fragmentation, followed
已经开发了通过钯催化的串联反应的3-氰基吲哚的新颖和快速的构建。获得“ NH”无保护基的N-烷基和N-芳基3-氰基吲哚,收率为好至极好。这种合成方法的实用性通过成功合成实用化合物(例如治疗性雌激素受体配体A前体)得到进一步证明。机理研究表明,串联催化利用了Suzuki交叉偶联以及随后的碱诱导的异恶唑片段化,然后是醛亚胺缩合。
