They serve as a key structural motif in pharmaceuticals and agrochemicals, making their efficient and sustainable synthesis highly desirable. The nucleophilic nature of hydroxy groups often alters the reaction pathway towards the formation of oxygen-bonded tetracyclic derivatives and lactonization byproducts, which is a significant challenge for the synthesis of 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-SO₃H) as a metal-free heterogeneous catalyst. The reaction proceeded in ethanol at a suitable reaction 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-SO₃H is attributed to its abundant –SO₃H functional groups, which enhance 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. Compared to conventional methods that yield an undesired side product, this approach ensures high selectivity and cleaner synthesis. The developed strategy not only aligns with the principle but also demonstrates the potential of sulfonated graphene oxide as a sustainable catalyst for organic transformation.</p><p>We apologize for these errors.</p>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 10","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aoc.70398","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
