Concise Synthesis of Spiro[indoline‐3,2′‐pyrrolidine] and 1‐Azacarbazole Derivatives via Copper‐Catalyzed Cyclization of Indoles

A high‐yielding, copper‐catalyzed dearomatization reaction of indole from 2‐methylindole‐derived oxime acetates was realized, providing access to structurally novel spiro[indoline‐3,2′‐pyrrolidine] derivatives in 67–98% yields. When the C‐2 position of the indole was not substituted, azacarbazole de...
