Oxidation of diazenyl-protected N-heterocycles-a new entry to functionalized lactams

Petrović, Martina; Scarpi, Dina; Nieger, Martin; Jung, Nicole; Occhiato, Ernesto G.; Bräse, Stefan

unctionalized lactams are an important class of heterocycles since they are useful intermediates in organic synthesis and show biological activity in diverse therapeutic applications. In the herein presented study, a strategy for the synthesis of N-aryldiazenyllactams, offering the direct access to protected lactam derivatives is described. After the formation of triazenes from diazonium salts and commercially available N-heterocycles, oxidation (directed CH activation) with periodate under ruthenium catalysis furnished N-diazenyllactams in one step. To demonstrate the suitability of the resulting lactams for further functionalizations, the alkylation of a N-diazenyllactam is presented for one example.
