  镍催化的Domino Heck环化/ Suzuki偶联反应合成3,3-二取代的吲哚

  摘要：

  报道了第一个镍催化的多米诺Heck环化/ Suzuki偶联反应，用于合成带有季全碳中心的3,3-二取代的羟吲哚。各种各样的亲电试剂，例如芳基碘化物，溴化物，三氟甲磺酸盐和氯化物，都与反应条件兼容。此外，廉价的芳基酯经过催化的C-O键裂解，也可以用作亲电子试剂。该方法显示出良好的产率和广泛的范围，补充了常规钯基类似物的更实用和可持续的替代方法。

  A Ni-catalyzed enantioselective reductive diarylation of activated alkenes by domino cyclizative/ cross-coupling of two aryl bromides is developed. This reaction proceeds under very mild conditions and shows broad substrate scope, without requiring the use of preformed organometallic reagents. Moreover, this approach provides direct access to various bis-heterocycles bearing all-carbon quaternary centers in synthetically useful yields (up to 81%) with excellent enantioselectivity (>30 examples, 90-99% ee).

  An exoselective copper-catalyzed arylation and vinylation-carbocyclization of electron-deficient alkenes was developed to provide rapid and efficient access to a variety of functionalized 3,3-disubstituted oxindoles. With this method, a highly efficient and concise formal synthesis of (+/-)-physostigmine and (+/-)-physovenine has been completed.

  Cu(OTf)(2)-catalyzed diarylation of activated alkenes by using diaryliodonium(III) salts has been developed. With this method, arylated oxindoles can be easily accessed in good yields. Insights into the mechanism of copper-catalyzed arylations are discussed, and the findings are expected to help increase the level of understanding of catalytic arylations with diaryliodonium salts.
