Chemoselective N-oxidation of picolinaldehydes with dimethyldioxirane
The N-oxidation of picolinaldehydes with dimethyldioxirane proceeds with remarkable selectivity. Especially the N-oxides of 3- and of 4- picolinaldehyde are isolated in high yields. The aldehyde-hydrate 3- dihydoxymethylpyridin-N-oxide was fully characterized.
