Über die Darstellung papaverinähnlicher Stoffe II

Abstract: 4632-(4-Methyl-pyridyl-3-)-chinolin-4-carbonsiiure 9,5 g 4-Methyl-3-acetyl-pyridin7) und 8 g Isatin werden in GO ccm Alkohol und 32 ccm 33%iger Kalilauge 4% Stunden unter Riickflud erhitzt. Die braunrote Losung wird wie bei der 2-(Pyridyl-~)chinolin-4-carbonsaure beschrieben, aufgearbeitet. Ausbeute an Rohprodukt 7 g (41% der Theorie).Zur Analyse wurde die Siiure iiber den Methylester gereinigt. Schmp. 235" C,,H,aO,N, (264,29) Ber. C 72,70 H 4,58 N 10,GO Gef.

“…204 In the reduction of oximes of a,b-unsaturated ketones, platinum dioxide is used as the catalyst and MeOH is used as the solvent. 205 The solvent has a substantial influence on the composition of the products of oxime reduction in the liquid phase. For example, when a more polar solvent was used, aziridine was obtained from benzylideneacetone oxime, in addition to the corresponding amine.…”
