  Polycyclic indolines and indolenines were synthesized via base-catalyzed intramolecular dearomatizing 3-alkenylation reactions of alkynyl indoles 1 at room temperature. The base enhanced the nucleophilicity of the carbon at the 3-position of the indole moiety, facilitating an exclusive 5-exo-dig cyclization reaction with the alkyne to form spiroindolenines 2. The imine functionality of 2 could undergo
