Counter-ion-dependent alkyne iminium ion cyclization for divergent synthesis of n -fused indolylidine, indole, and indoline derivatives promoted by the lewis/bronsted acid

Gharpure, Santosh J.,Shelke, Yogesh G.,Kumar, Dasari Praveen

, p. 1926 - 1929 (2015)

Divergent synthesis of N-fused indolylidine, indole, and indoline derivatives using alkyne iminium ion cyclization is described. Trapping of vinyl cation intermediate generated after alkyne iminium ion cyclization was found to be dependent on the Lewis/Br
