Abstract
A copper-catalyzed [2,3]-sigmatropic rearrangement of azide-ynamides via selenium ylides is disclosed, which leads to the practical and divergent synthesis of a variety of tricyclic heterocycles bearing a quaternary carbon stereocenter in generally moderate to excellent yields. Significantly, this method represents the first [2,3]-sigmatropic rearrangement of the selenium ylide based on alkynes and an unprecedented [2,3]-sigmatropic rearrangement via α-imino copper carbenes.

Abstract
A catalyst-free cascade reaction of 3-(2-isocyanoethyl)indoles and 1-sulfonyl-1,2,3-triazoles was realized. This dearomative spirocyclization provided an efficient protocol to synthesize a series of polycyclic indolines bearing spiro-α-carboline in moderate to high yields in one step under thermal reaction conditions.
