Abstract: Spiropyrimidines vanquish a significant situation in the field of heterocyclic chemistry, they are broadly utilized as an antibacterial, an inhibitor of multidrug opposition, or an antiplatelet and antithrombotic drug. Phosphate, the principal Moroccan mineral wealth occupies a vital spot in the economic sector and its valuation is a goal continually looked for. Among the conceivable outcomes of valorization, its utilization in heterogeneous catalysis which thought about an exceptionally encouraging new way. In this context, the focus on the reaction of the synthesis of spiropyrimidine, catalyzed by natural phosphate (NP) and by fluoroapatite (Fap), are used alone or doped by cobalt. These phosphate catalysts were characterized by XRD, IR and SEM, while the synthesized spiropyrimidine was identified by IR, GC–MS and NMR. The obtained yield with fluorapatite doped by cobalt (Co/Fap), at room temperature in ethanol is very high and shows a high impact performance induced by a synergistic effect compared to that of NP alone.
