pyrolysis of various N-(2′-hydroxyethyl)-3-amino propenoates 1–6 and N-(2′-hydroxy-2′-phenyl ethyl)-3-amino propenoate 7–9 at 390°–420°C leads respectively to formylpyrroles 11–16 and benzoylpyrroles 17–19 and, in some cases, to substituted oxazoles 36–39. The results are best explained by the intermediate formation of dicarbonyl derivative followed either by an intramolecular thermal crotonisation
A Convenient Synthesis of 2-Aroyl-5-arylpyrroles 2-Aroyl-5-arylpyrroles are prepared in 20-60% yields by cyclocondensation of 1,5-diaryl-2-methylsulfinyl-1,5-pentanediones with ammonium acetate in acetic acid.
