Chemoselective N-oxidation of picolinaldehydes with dimethyldioxirane
摘要:
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. (C) 1999 Elsevier Science Ltd. All rights reserved.
