Abstract :
Abstract: An efficient synthesis of imidazo oxazins is described using a reaction of activated dialkyl acetylenedicarboxylates with acid chloride and ethanol in the Presence of imidazole. In addition, for existing imidazol and oxazin core in the synthesized compounds, evaluation of antioxidant activity was performed by radical trapping by DPPH and reducing power of ferric ion experiments. As a result, synthesized compounds show low radical trapping by DPPH and good reducing ability of ferric ion. The current procedure has the benefits for instance excellent yield of reaction, green media and easy separation of product.
