Application of novel metal-organic framework [Zr-UiO-66-PDC-SO 3 H]FeCl 4 in the synthesis of dihydrobenzo[ g ]pyrimido[4,5- b ]quinoline derivatives

In the current paper, we produce a new metal-organic framework (MOF) based on Zr metal, [Zr-UiO-66-PDC-SO H]FeCl , an anion exchange method, which is fully characterized by FT-IR, SEM with elemental mapping and EDX, FE-SEM and TEM. Furthermore, the use of [Zr-UiO-66-PDC-SO H]FeCl as a porous catalyst was examined for the one-pot synthesis of novel dihydrobenzo[ ]pyrimido[4,5- ]quinoline derivatives by reaction of 6-amino-1,3-dimethylpyrimidine-2,4(1 ,3 )-dione, 2-hydroxynaphthalene-1,4-dione and various aldehydes at 100 °C with good to excellent yields.
