Rh(III)-Catalyzed Tandem C–H Allylation and Oxidative Cyclization of Anilides: A New Entry to Indoles
摘要:
Rh-III-catalyzed tandem C-H allylation and oxidative cyclization of anilides with allyl carbonates in the presence of a slight excess of AgSbF6 salt and Cu(OAc)(2) as oxidant affords easy, economical access to important bioactive 2-methylindoles. The new reaction supports a wide range of functional groups on the anilide substrate. A possible mechanism is proposed as a basis for its rational further development.

Tandem rhodium-catalyzed oxidative allylation and annulation of acetanilides with allyl acetate to afford the corresponding indoles are described. In addition, the site-selective C2 allylation, crotylation and prenylation of indoles using allylic acetates under rhodium catalysis are reported.
