The nucleophilic nature of hydroxy groups often alters the reaction pathway towards the formation of oxygen-bonded tetracyclic derivatives and lactonization by-products, which is a significant challenge for the synthesis of dihydropyrimidinone derivatives (DHPM) with ortho-hydroxy groups. In the present study, a highly promising and environmentally friendly protocol has been developed for the synthesis of DHPM derivatives using sulfonated graphene oxide (GO-HSO<sub>3</sub>) as a metal-free heterogeneous catalyst. The reaction proceeded in ethanol at room temperature, rendering a sustainable and greener approach. The catalytic system efficiently facilitated the Biginelli reactions between ethyl acetoacetate, urea, and azo salicylaldehyde or salicylaldehyde, leading to the selective transformation of DHPMs with excellent yields (84–94%) and minimal byproducts. The superior catalytic activity of GO-HSO<sub>3</sub> is attributed to its abundant –SO<sub>3</sub>H functional groups, which enhance the proton donation and reaction kinetics. This approach is a sustainable and practical method for DHPM synthesis due to its excellent yield, ease of execution, reusability of the catalyst, and adherence to green chemistry principles.
