摘要： 3-Cyano-4-arylpyrroles of the formula (I) in which Ar represents in each case substituted or unsubstituted heteroaryl or aryl, are prepared by reacting alpha -cyanoacrylic acid derivatives of the formula (II) in which Ar has the abovementioned meaning and R represents amino or alkoxy with isocyanoacetic esters of the formula (III) in which R represents alkyl in the presence of a base and, if desired, in the presence of a diluent and subjecting the DELTA -pyrroline-2-carboxylic acid derivatives thus obtainable of the formula (IVa) in which X represents hydrogen or one equivalent of an inorganic or organic cation and Ar has the abovementioned meaning to oxidative decarboxylation in a 2nd step in the presence of a base and in the presence of a metal salt and, if desired, in the presence of a diluent.
