| Abstract | ||
| The aim of the present study is to synthesis of new (19) compounds of 4-methyl coumarinderivatives,starting by (5,7-dihydroxy-4-methyl-2-H-coumarin-2-one). Avariety of shiff bases and heterocyclic (oxazepine ) have been synthesized the proposed structures were confirmed by physical properties , UV –Visible, FT-IR and ¹ H NMR. | ||
