Rhodium(III)‐Catalyzed Selective CH Cyanation of Indolines and Indoles with an Easily Accessible Cyano Source

Abstract

Abstract The rhodium‐catalyzed selective cyanation of CH bonds of indolines and indoles with N ‐cyano‐ N ‐phenyl‐ para ‐methylbenzenesulfonamide is described. This protocol offers a facile access to C‐7 cyanated indolines and C‐2 cyanated indoles with high site selectivity and excellent functional group tolerance. magnified image
