A simple methodology for the conversion of substituted N-aryl-gamma-lactam 2/3-carboxylic acids to substituted N-aryl-diformylated pyrroles has been developed. Several gamma-lactam 2/3-carboxylic acids were subjected to Vilsmeier reagent and substituted diformylated pyrroles are isolated in one-step process. (C) 2009 Elsevier Ltd. All rights reserved.
