Abstract

OSORNIO, Yazmín M.; MIRANDA, Luis D.  and  MUCHOWSKI, Joseph. M.. Intramolecular Radical Addition to the 2-Pyridone Nucleus. Rev. Soc. Quím. Méx [online]. 2004, vol.48, n.4, pp.283-287. ISSN 0583-7693.

The radical species derived from the N-ω-haloalkylpyridones 4b, 6c and the xanthates 7a, 7b undergo oxidative cyclization to the bicyclic 2-pyridone derivatives 8a-c irrespective of whether they are generated under reductive (Bu₃SnH/AIBN) or oxidative [Fe(II)/H₂O₂/DMSO or DLP] conditions.

Keywords : 2-pyridone; radical cyclization; Fenton; xanthates; dilauroyl peroxide.
