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.
Pyrazinamide compounds, preparation method and application thereof as well as bactericide

Paragraph 0140-0143, (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.

A fast and efficient palladium-catalyzed fourfold domino Sonogashira/double-carbopalladation/C H-activation reaction that converts simple aromatic systems into complex polycyclic hydrocarbons has been developed. A number of substituted products has thus been prepared in yields up to 89 %. The structural assignment has been confirmed by using single-crystal X-ray crystallography. The products show intriguing fluorescence activity and thus might serve as chemical sensors or fluorescent imaging dyes.
