Rhodium(III)-Catalyzed Redox-Neutral C-H Annulation of Arylnitrones and Alkynes for the Synthesis of Indole Derivatives
Zhou, Zhi,Liu, Guixia,Chen, Yan,Lu, Xiyan
, p. 2944 - 2950 (2015)
By using a nitrone as the oxidizing directing group, a mild, practical and efficient rhodium(III)-catalyzed C-H functionalization for the synthesis of indole derivatives has been developed. This reaction obviates the need for an external oxidant and shows good functional group tolerance. The employment of a sterically hindered Mes group on the carbon center of the nitrone is crucial to produce indoles in high yield.

Paragraph 0029-0031; 0034; 0036, (2018/04/26)
The invention provides a method for preparing indole compounds by using rhodium/carbon as a catalyst. Corresponding indole compounds are formed through subjecting aniline and analogs thereof and alkyne to a catalytic cyclization reaction in the presence of the rhodium/carbon. The method has the beneficial effects that the preparation method is simple in process, the raw materials are cheap and readily available, the yield is high, inert-gas protection is not required, and the reaction temperature is relatively moderate.
