    Description / Table of Contents: Zusammenfassung Die Reaktion von β-Morpholino-thiozimtsäureaniliden1 mit Malononitril lieferte 2-Arylimino-thiopyrane3, die unter alkalischen Bedingungen zu 6-Thioxo-pyridinen5 umgesetzt wurden. Die Struktur der dabei erhaltenen Verbindungen wurde mittels chemischer und spektroskopischer Eigenschaften zugeordnet. Der Mechanismus der Konversion von3 zu5 wird diskutiert.
    Notes: Abstract The reaction of β-morpholino-thiocinnamic acid anilides1 with malononitrile yielded 2-arylimino-thiopyrans3, which in turn were converted under alkaline conditions into 6-thioxo-pyridines5. Their structures were elucidated on the basis of chemical properties and spectral data. The mechanism of the conversion3 into5 is discussed.

    TheKnoevenagel reaction of malononitrile with some cyclic β-ketocarbothionic acid anilides synthesis of cycloalkeno-pyridines and cycloalkeno-thiopyrans (1982)
    Springer
    Monatshefte für Chemie 113 (1982), S. 583-592

    Description / Table of Contents: Zusammenfassung Es wird ein neuer Zugang zu Cycloalkeno[c]pyridinen (2) und Cycloalkeno[c]thiopyranen (5) mittels Reaktion von Malononitril mit Enaminen cyclischer β-Ketocarbothionsäureaniliden aufgezeigt. Die Strukturaufklärung der erhaltenen Verbindungen basiert auf massenspektroskopischen Daten. Die Reaktion wird als Folge von Addition, Eliminierung und Cyclisierung diskutiert.
    Notes: Abstract A new route to the cycloalkeno-pyridines2 and cycloalkeno-thiopyrans5 by the reaction of malononitrile with enamines of cyclic β-ketocarbothionic acid anilides is presented. The elucidation of the structure of compounds obtained is based on MS spectral data. The reaction is proposed to be a sequence of addition, elimination and cyclization.

    The Reaction of Malononitrile with Enamines of some cyclic β-Keto acid anilides and amidines (1984)
    New York, NY : Wiley-Blackwell
    Journal für Praktische Chemie/Chemiker-Zeitung 326 (1984), S. 721-728 
    Details
    ISSN: 0021-8383
    Keywords: Chemistry ; Organic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The reaction of enamines 1 derivatives of cyclohexanon- or cycloheptanon-2-carboxylic acid anilides with malononitrile gave in the first step 2-phenylcarbamoyl-cycloalkylideno-malononitriles 3, which in turn were converted into 1-oxo-2-phenyl-3-amino-4-cyano-cycloalkenoisoquinolines 4. Enamines containing an adjacent diphenylamidino group 6 reacted with malononitrile giving 1-phenylimino-2-phenyl-3-amino-4-cyano-cycloalkenoisoquinolines 7. The alkaline hydrolysis of 7 yielded 1-phenylamino-3-oxo-4-cyano-cycloalkenoisoquinoline 8.
