A novel porphyrin cored amine functionalized dendritic polymer was effectively synthesized by divergent method. It was identified as an effective homogeneous organo catalyst for the synthesis of quinoline derivatives, from aromatic aldehyde, aromatic amine and malononitrile. The reaction was completed within one hour with high yield (87% ‐ 93%) in 2:1 ratio of water and ethanol medium at 60 °C. Porphyrin cored dendritic polymer has a number of amino groups on its surface; hence it acts as a very good base catalyst. Separation and reuse of the catalyst from the product was easy due to its water soluble nature. This is the first reported synthesis of Quinoline derivatives using dendritic polymer as an organo catalyst.
