Microwave‐assisted Synthesis of Dihydro Dibenzophenanthroline and Its Derivatives Using a Self‐catalyzed Friedlander Reaction. (18th October 2018) - Chandraprakash, Kumarasamy
Abstract : One‐step microwave‐assisted synthesis of dihydro dibenzophenanthrolines are reported using a self‐catalyzed Friedlander reaction. The reaction is carried out in one step by simple microwave irradiation of 3, 4‐dihydroacridin‐1(2 H )‐one with 2‐amino‐benzophenone in the presence of acid catalysts with solvent‐free conditions. Thin‐layer chromatography was used to monitor the progress of the reaction; hence, it was observed that the reaction starts slowly and accelerates as it proceeds to ring fusion transformation. Synthesized compounds' isolated yield is enhanced in the absence of solvent systems with Friedlander catalyst under microwave irradiations. Abstract :
