Abstract:

In recent years, with the growing awareness of environmental issues, the demand for the development of environmentally friendly catalysts has been increasing rapidly. These catalysts must be designed and synthesized in such a way that while increasing the reaction rate and yield, they cause minimal harm and pollution to the environment. In this regard, the chemical science community has conducted extensive research and designed and synthesized various types of catalysts, including nanowires. Due to their unique set of properties, including special chemical and physical properties, high surface area, and regular crystal structure, these nanocatalysts have emerged as ideal and promising candidates for catalyzing multi-component reactions. Therefore, manganese oxide nanowires (MnO۲ NWs) were synthesized in this study using an eco-friendly and cost-effective method and characterized using techniques such as FT-IR, XRD, and SEM. Naphthopyranopyrimidines are an important class of organic compounds that have attracted the attention of researchers in recent decades due to their chemical and pharmaceutical activities in the synthesis of a wide range of heterocyclic compounds. In this study, the synthesis of naphthopyranopyrimidine derivatives was carried out in the presence of manganese oxide nanowires (MnO۲ NWs) under solvent-free conditions. All products were synthesized with excellent yields in a short reaction time. Other advantages of this method include high speed, biocompatibility, and a clean reaction pathway.
