This method employs 2,2’-bipyridine as a cost-effective and proficient organo-catalyst. All reactions take place within reasonable reaction periods, yielding favorable to excellent results. The reusability of the catalyst is also investigated during the reactions. Moreover, a rational mechanism was suggested via GC-Mass analysis of the trapped intermediates. Research Highlights 2,2′-bipyridine as an excellent basic catalyst for the synthesis of pyrano[2,3-d]pyrimidines and pyrido[2,3-d]pyrimidines in the aqua media. Simple procedure, short reaction times, and high yields. No column chromatographic separation, commercial availability and recyclability of the catalyst. Use of GC-Mass analysis for the confirmation of the proposed mechanism. }, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Surchani, Mandana Momenpour and Shirini, Farhad and Tajik, Hassan and Jolodar, Omid Goli}, year={2024}, month={Aug.}, keywords={Pyrano[2, Organo-catalyst, Pyrido[2, One-pot synthesis, 3-d]pyrimidines, 2, 2’-bipyridine} }
