An Efficient Synthesis of Polyfunctionalized Indole Derivatives via Three‐component Domino Reaction Catalyzed by L‐Proline. (12th June 2014) - Fu, Lei
Abstract A facile and efficient one‐pot procedure for the preparation of indeno[1, 2‐b]indole derivatives via three‐component domino reaction of ninhydrin, enaminones, and malononitrile catalyzed by L‐proline is described. In this reaction, two rings and four bonds were formed by one‐pot.
