N2 - In this work, a highly efficient technique has been documented for the one-pot synthesis of pyrano[2,3-d]pyrimidine and pyrido[2,3-d]pyrimidine derivatives. 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.
