A facile protocol for the synthesis of phenoxazines and benzopyridoxazines by Smiles rearrangement have been demonstrated in short reaction time under microwave irradiation. The control experiments suggest that a reaction proceeds through Smiles rearrangement followed SNAr ring closure by in situ cascade process. In our present work, both the electron donating and electron withdrawing groups were tolerant and provided a corresponding phenoxazine/benzopyridoxazine in good to moderate yields.

Paragraph 0143; 0171; 0172, (2018/06/04)
The invention relates to the field of pesticide bactericides and discloses pyrazinamide compounds, a preparation method and an application thereof as well as a bactericide. The compounds have the structure shown in formula (I). The pyrazinamide compounds with the novel structure are designed by introducing pyrazine ring fragments in Pyradiflumid and diphenyl ether fragments with wide bioactivity,and the pyrazinamide compounds can be used as novel SDHIs (succinate dehydrogenase inhibitors) or bactericides.
