Aryl-2 et alkyl-2 quinoléines nouvelles isolées d'une Rutacée bolivienne: Galipealongiflora

Abstract

Five new 2-aryl and 2-alkyl quinoline alkaloids were obtained from Galipeallongiflora Krause (Rutaceae). These are 2-phenylquinoline 1, 2-(3′,4′-methylenedioxyphenethyl)quinoline 2, 2-(3′,4′-dimethoxyphenethyl)quinoline 3, 2-(3′,4′-methylenedioxystyryl)-4-methoxyquinoline 4, and 2-(1′,2′-pentenyl)-4-methoxyquinoline 6. They are accompanied by three known 2-substituted quinolines, 2-n-amyl-4-methoxyquinoline 5, 2-(3′4′-methylenedioxyphenethyl)-4-methoxyquinoline 7, and 2-phenyl-4-methoxyquinoline 8, and by two known furo[2,3b]quinoline alkaloids: evolitrine and skimmianine. Keywords: Galipealongiflora, Rutaceae, new quinolines.
