Recently, conjugated nanomaterials made of a nano-metal oxides core and polymers have emerged as a promising candidate in new generation catalysis. Herein, we report a novel heterogeneous catalyst by immobilizing poly triazine-thiourea-sulfonamide (PTTSA) on the surface of the Zn-Al-Cu core. In this sense, the sulfonated catalyst was obtained via simple sulfonation using chlorosulfonic acid (Zn-Al-Cu@PTTSA-SO3H). The post-synthetically modified nanomaterial was characterized using FT-IR, FE-SEM, TGA, EDX, XRD, and WDX. Regarding the catalytic exploration, we aimed at synthesizing furano and pyrano pyrimidinone derivatives via a one-pot three-component reaction of urea/thiourea, 2,3-dihydrofuran/3,4-dihydro-2H-pyran, and aldehydes with a variety of substrates. The catalyst is highly reusable and efficient, especially in terms of time and yield of the desired product.
