L-Prolin anchored on mesoporous SBA-15: A new recyclable catalyst to the synthesis of pyrimidines

The Heterogenization of catalyst prospers the recycling properties along with improving the performance of them. Ordered mesoporous silica show high ability to be an environmentally benign catalyst.[1] They have a robust structure with high surface area to use in the industries. As regard to the pore size of them, especially SBA/15 can be functionalized by organic compound in order to develop the application in catalysis.[2] In this research the novel organic–inorganic hybrid catalyst by N-Functionalized L-Proline anchored SBA/15 was synthesized. The structure of 2D-hexagonally ordered mesophases of catalyst characterized by FTIR spectroscopy, N2 adsorption analysis, scanning electron microscope, X-ray diffraction spectroscopy. The activity of catalyst has been scrutinized by synthesizing pyrimidine that showed biological anti-bacterial activities.[3] The process of the synthesis of these compounds might be followed by tautomeric interconversion but in the presence of L-proline@SBA-15 catalyst, the reaction stopped at this stage. small angle X-ray diffraction pattern of prior and after the incorporation of the bidentate complex shows an intense diffraction peak at (1 0 0), (1 1 0) and (2 0 0).
