O 4 supported on MIL-100 (Cr) for the synthesis of pyrido [2, 3-d] pyrimidine derivatives via
the three-component one-pot reaction of 1, 3-indandione, 6-amino uracil, and aromatic
aldehydes is reported. The effectiveness of this new magnetic nanocatalyst was proved. The
results showed this nanocatalyst's moderate to high yield under reflux conditions. SEM,
TEM, IR, EDX, XRD, BET, and TGA were used to characterize the structure of the …
