TEMPO-Mediated Aliphatic C–H Oxidation with Oximes and Hydrazones
摘要:
A method for aliphatic C-H bond oxidation of oximes and hydrazones mediated by 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) has been developed, which enables the concise assembly of substituted isoxazole and pyrazole skeletons.

The syntheses of β,β-diaryl aryl propiophenones have been realized via palladium-catalyzed domino reactions of dimethyl amino functionalized enaminones and aryl boronic acids. This is the first example of transition metal-catalyzed enaminone C–N bond conversion for the generation of a new C–C(aryl) structure.
