Skraup chinolinesynthese

WebbAn Ir-catalyzed synthesis of functionalized quinolines from 2-aminobenzyl alcohols and α,β-unsaturated ketones tolerates a broad range of functional groups, offers high efficiency, is environmentally benign, and can be performed on a gram scale. Alkali is essential for the high selectivities of this catalytic system. Die Skraup-Synthese wurde nach dem tschechisch-österreichischen Chemiker Zdenko Hans Skraup (1850–1910) benannt, und beschreibt die Synthese von Chinolin und dessen Derivaten aus Anilin, Schwefelsäure, Eisen(II)-sulfat und Glycerin. Die Dehydrierung der Zwischenstufe 1,2-Dihydrochinolin erfolgt durch Nitrobenzol.
