A concise and facile method for the synthesis of heterocyclic compounds with NO tether was introduced. The two important steps of the synthesis are a Mitsunobu reaction and CH activation. The Mitsunobu protocol allows to form the NOmoiety in the molecule, while subsequent CH activation leads to heterocycles.

We report a facile approach to a cyclopropyl-fused pyrrolidine, which contains four stereogenic centers, by employing the N–O tethered carbenoid methodology. The synthesis was facilitated by the development of a direct Mitsunobu reaction of alcohols with N-alkyl-N-hydroxyl amides to give diazo precursors, which upon intramolecularcyclopropanation yielded a library of N–O containing cyclopropyl-fused

Diazocarbonyl compounds are versatile precursors of carbenes leading to various structures by using several metal catalysts, especially copper and rhodium salts. In this study, eight different diazocarbonyls having N-O moiety were used. The N-O tethered structures were preferred because they may allow some useful transformations of the final products into valuable compounds via N-O cleavage. In the
