Herein, we describe the iron(III)-catalyzed oxidative coupling of alcohol/methyl arene with 2-amino phenyl ketone to synthesize 4-quinolone. Alcohols and methyl arenes are oxidized to the aldehyde in the presence of an iron catalyst and di-tert-butyl peroxide, followed by a tandem process, condensation with amine/Mannich-type cyclization/oxidation, to complete the 4-quinolone ring. This method tolerates
在本文中,我们描述了铁/(III)催化的醇/甲基芳烃与2-氨基苯基酮的氧化偶联,以合成4-喹诺酮。在铁催化剂和二叔丁基过氧化物的存在下,将醇和甲基芳烃氧化为醛,然后进行串联反应,与胺/曼尼希型环化/氧化反应缩合,完成4-喹诺酮环。该方法可耐受各种官能团,并提供了直接从功能化程度较低的底物合成4-喹诺酮的方法。
