    Description / Table of Contents: Synthesis of 5-Oxo-pyrrolines via Acyl-enehydrazines5-Oxo-pyrrolines 3 are obtained in good yields by heating acyl-enehydrazines 2 with sodium methylate. This synthesis constitutes a convenient new general method of preparation of pyrrolinones. - Acyl-hydrazones 18 lead to 5-oxo-pyrrolines only in special cases. The mechanism of the pyrrolinone synthesis is discussed.
    Notes: Acyl-enhydrazine 2 lassen sich durch Erhitzen mit Natriummethylat in guten Ausbeuten in 5-Oxo-pyrroline 3 überführen. Diese neue Pyrrolinonsynthese ist verallgemeinerungsfähig. - Aus Acyl-hydrazonen 18 entstehen 5-Oxo-pyrroline nur in speziellen Fällen. Der Mechanismus der Pyrrolinonsynthese wird diskutiert.
