The gold-catalyzed Friedlander reaction was applied to the condensation of 2-aminoarylketones with β-keto-esters, β-diketones, β-keto-amides, and β-keto-sulfones to afford a diverse range of 2,3,4-trisubstituted quinolines in 3–82% yield. The seven-membered rings 1,3-cycloheptadione and azepane-2,4-dione reacted smoothly in 75% yield. An alternative procedure for the synthesis of 3-(methanesulfonyl)quinolines
金催化的弗里德兰德反应用于2-氨基芳基酮与β-酮酯,β-二酮,β-酮酰胺和β-酮砜的缩合反应,从而得到范围广泛的2,3,4-三取代喹啉,产率3–82%。七元环1,3-环庚二酮和氮杂环庚烷-2,4-二酮反应平稳,产率为75%。开发了另一种合成3-(甲磺酰基)喹啉的方法,并为进入后期操作这些喹啉的4-位开辟了道路。Friedlander反应所需的2-氨基芳基酮是在一锅中通过改良的Sugasawa反应使用氯化镓(III)和氯化硼(III)制备的,产率为12-54%。
