Paragraph 0073; 0087; 0088, (2017/08/08)
The invention discloses a method for catalytic oxidation of phenolic compounds fragrant boron class compound synthesis method, the flux in the solvent in the aqueous solution, under the action of alkali, adding hydrazine hydrate or acid hydrazides catalyst, catalytic oxidation fragrant boron class compound directly for the preparation of phenolic compound. The invention of the method of preparation of the phenol compound, the catalyst is a cheap hydrazine hydrate or hydrazine compound, the oxidizing agent is atmospheric pressure of air or oxygen, the reaction does not need good and activeness metal catalyst, is extensive and stable substrate, substrate-sensitive functional group compatibility good and wide range of application. In the optimized under the reaction conditions, the yield of the target product separation up to 99%. (by machine translation)

The yield of 9-alkylamino-5H-pyridoazepines from the photo-induced ring-expansion of 8-azidoquinoline in primary amines are increased significantly by the presence of a 6-methoxy group, which also for the first time induces ring-expansion of the azide in secondary amines.Optimum conditions have been found for the ring-expansion of 8-azidoquinoline in methanol-potassium methoxide to give 9-methoxy-5H-pyridoazepine, and under the same conditions 8-azido-6-methoxy- and 6-azido-8-methoxy-quinoline ring-expand in excellent yield to the corresponding dimethoxypyridoazepines.
