Unusual ring transformation of N-hydroxy-3,5-dinitro-4-pyridone Affording a polyfunctionalized pyrrole

, 2008
Polyfunctionalized pyrrole 6 is synthesized in the ring transformation of N-hydroxy-3,5-dinitro4-pyridone 4 with enolate 2 derived from diethyl 3-oxogulutarate. The present reaction proceeds with C-N transfer from 4 to 2, which is hitherto unknown manner
