La Síntesis de quinolinas de Conrad-Limpach es un método de síntesis orgánica donde se hacen reaccionar anilinas (1) con β-cetoésteres (2) para formar 4-hidroxiquinolinas (4) a través de una base de Schiff (3).​​​ Se han publicado diversos estudios de esta reacción.​​ Sintesis Conrad-Limpach adalah sebuah reaksi kimia antara anilina (1) dengan β-ketoester (2) membentuk 4-hidroksi (4) via (3). Beberapa tinjauan telah dipublikasikan. Conrad–Limpach合成(Conrad–Limpach synthesis) 芳胺与β-在加热条件下发生缩合为亚胺,然后进行环化,得到4-羟基喹啉或其衍生物。 反应综述: The Conrad–Limpach synthesis is the condensation of anilines (1) with β-ketoesters (2) to form 4-hydroxyquinolines (4) via a Schiff base (3). The overall reaction type is a combination of both an addition reaction as well as a rearrangement reaction. This reaction was discovered by (1848–1920) and Leonhard Limpach (1852–1933) in 1887 while they were studying the synthesis of quinoline derivatives. Die Conrad-Limpach-Chinolinsysnthese ist eine Namensreaktion aus dem Bereich der organischen Chemie und wurde 1887 von Max Conrad (1848–1920) und Leonhard Limpach (1852–1933) beschrieben. Dabei findet unter Abspaltung von Wasser und Alkohol eine Kondensation von Anilin mit einem β-Ketoester zu einem statt. De Conrad-Limpach-synthese is een organische reactie, waarbij een aniline (1) met een β-ketoester (2) omgezet wordt tot een Schiff-base (3), die daaropvolgend verhit wordt tot het overeenkomstige hydroxychinolinederivaat (4): De reactie vertoont grote gelijkenissen met de Combes-chinolinesynthese.

Die Conrad-Limpach-Chinolinsysnthese ist eine Namensreaktion aus dem Bereich der organischen Chemie und wurde 1887 von Max Conrad (1848–1920) und Leonhard Limpach (1852–1933) beschrieben. Dabei findet unter Abspaltung von Wasser und Alkohol eine Kondensation von Anilin mit einem β-Ketoester zu einem statt. Sintesis Conrad-Limpach adalah sebuah reaksi kimia antara anilina (1) dengan β-ketoester (2) membentuk 4-hidroksi (4) via (3). Beberapa tinjauan telah dipublikasikan. The Conrad–Limpach synthesis is the condensation of anilines (1) with β-ketoesters (2) to form 4-hydroxyquinolines (4) via a Schiff base (3). The overall reaction type is a combination of both an addition reaction as well as a rearrangement reaction. This reaction was discovered by (1848–1920) and Leonhard Limpach (1852–1933) in 1887 while they were studying the synthesis of quinoline derivatives.
