摘要:

三价铑在氧化还原中性条件下催化硝酮与炔发生偶联, 经过氮芳环的碳氢键活化和氧转移可以高化学选择性、中等到良好非对映选择性的得到三取代二氢吲哚.

关键词: 三价铑, 碳氢活化, 氧转移, 氮芳基硝酮

Abstract:

Rh-catalyzed redox-neutral coupling between N-aryl nitrones and alkynes has been achieved under relatively mild conditions. The reaction proceeded via C-H activation at the N-aryl ring with subsequent O-atom transfer, affording trisubstituted indolines in good chemoselectivity and moderate to good diasteroselectivity.

Key words: Rhodium(III), Carbon-hydrogen activation, Oxygen-atom transfer, Nitrogen-aryl nitrones
