In this research project, new derivatives of New derivatives of 5H -chromeno [3,4-b] pyridine- 5-one have been synthesized. These derivatives have been synthesized from the reaction between the vinamidinium salts with 4-hydroxyaminocoumarin in the presence of the N-ethyl di isopropylamine in the DMF (Fig. 1). The structures of these new compounds have been identified by analysis, 1H NMR, and 13C NMR spectroscopy.
