One-Pot Synthesis of Pyrrolo[1,2-a]quinolin-1-ones by the Cyclocondensation of 5-Hydroxy-1-arylpyrrolidin-2-ones with Dicarbonyls.
ChemInform(2013)
Abstract
The transformation proceeds as a two-step process consisting of an initiatory acid-catalyzed coupling reaction between N-acyliminium ions and 1,3-dicarbonyls followed by a phosphorus pentoxide or sulfuric acid-promoted intramolecular Friedel-Crafts acylation.
