Described herein is the development of a desaturation and N-βnitration reaction of cyclic amides, which is achieved by a selective hydrogen atom transfer (HAT)/oxidative desaturation/ electrophilic nitration process. In this procedure, di-tert-butyl peroxide (DTBP) acted both as the oxidant and HAT reagent, and electrophilic NOBF 4 as nitration source. Notably, the application of produced cyclic nitroene-sulfonamides was showcased by their efficient transformations into 3-piperidones and poly-substituted piperidine derivatives.
