    Description / Table of Contents: Abstract o-Aminophenylglyoxal-dimethylacetal (1) has been condensed with several cyclic ketones, acetophenones, and with acetone to yield derivatives of quinoline-4-aldehyde.1 reacts with ethyl acetoacetate and diethyl malonate at 160° yielding 3-acetyl-(11) and 3-carbethoxy-4-dimethoxymethyl-carbostyril (12) respectively. o-Acetaminophenylglyoxal dimethyl acetal (21) undergoes ring closure to carbostyril-4-aldehyde dimethyl acetal (22), when treated with sodium ethoxide; the reaction of21 with ethyl cyanoacetate leads to 3-cyano-4-dimethoxymethyl-carbostyril (24).
    Notes: Zusammenfassung o-Aminophenylglyoxal-dimethylacetal (1) läßt sich mit Carbonylverbindungen, die eine α-Methylengruppe enthalten, im Sinne einerFriedländer-Synthese zu Derivaten des Chinolin-4-aldehyds umsetzen. Bei 150–160° reagiert1 mit Acetessigester und Malonester unter Bildung des 3-Acetyl-(11) bzw. 3-Car-bäthoxy-4-dimethoxymethyl-carbostyrils (12). o-Acetaminophenylglyoxal-dimethylacetal (21) kann mit Na-Äthylat zum Carbostyril-4-aldehyd-dimethylacetal (22) cyclisiert werden; mit Cyanessigester kondensiert sich21 zum 3-Cyan-4-dimethoxy-methyl-carbostyril (24).

    Description / Table of Contents: Abstract The reaction of benzoylacetone with malonylchloride yields according toButt andElvidge 1 5-acetyl-4-hydroxy-6-phenyl-2-pyrone, wich is isomerised at 168° to an isomeric compound with a m. p. of 220°. However the physical properties of these two products are not in agreement with the previously1 postulated simple keto-enol-tautomerism between these compounds.
    Notes: Zusammenfassung NachButt undElvidge 1 reagiert Benzoylaceton mit Malonylchlorid zu 4-Hydroxy-5-acetyl-6-phenyl-pyron-(2) (Schmp. 168°), welches beim Erhitzen auf 168° ein Isomeres vom Schmp. 220° gibt. Die Formulierung dieser beiden Verbindungen als Keto-Enol-Tautomere wird auf Grund verschiedener physikalischer Daten widerlegt.
