Access to Polycyclic Sulfonyl Indolines via Fe(II)-Catalyzed or UV-Driven Formal [2 + 2 + 1] Cyclization Reactions of N-((1H-indol-3-yl)methyl)propiolamides with NaHSO<sub>3</sub>
A variety of structurally novel polycyclic sulfonyl indolines have been synthesized via FeCl2-catalyzed or UV-driven intramolecular formal [2 + 2 + 1] dearomatizing cyclization reactions of N-(1H-indol-3-yl)methyl)propiolamides with NaHSO3 in an aqueous medium. The reactions involve the formation of one C–C bond and two C–Sbonds in a single step.
An enantioselective desymmetric nucleophilic α‐addition of cyclohexanone to propiolamide has been developed through a 6‐exo‐dig cyclization reaction. By employing simple and readily available L‐proline sodium salt as a bifunctional catalyst, a series of chiral 6,6‐bicyclic bridged products bearing morphan scaffold have been isolated in good yields and excellent enantioselectivities.

Copper catalysed domino decarboxylative cross coupling-cyclisation reactions: synthesis of 2-arylindoles
The efficient synthesis of 2-arylindoles and 6H-isoindolo[2,1-a]indol-6-one through copper catalysed domino sp-sp(2) decarboxylative cross-coupling and subsequent cyclisation reactions of arylpropiolic acids with 2-iodotrifluoroacetanilide has been described. This methodology also demonstrates that indolo[1,2-c]quinazolin-6(5H)-one can be obtained with the elimination of trifluoromethyl anion. (C) 2012 Elsevier Ltd. All rights reserved.
