Microwave activation in the synthesis of nitrogen heterocycles, N-oxides of pyridine series
摘要:
Oxidation of heterocycles of the pyridine series under conditions of microwave irradiation was studied. It is established that oxidation of pyridine and 4-methylpyridine with hydrogen peroxide results in the corresponding N-oxides, and oxidation of 3-(piperidin-2-yl)pyridine gives delta-oximino-delta-(pyridyl-3-N-oxide)valeric acid.
