facile and practical approach to the synthesis of a wide range of functionalized quinolines was developed via a tandem heteroannulation reaction of o-aminoarylketones with diverse α-methylene ketones in high yields by using tetrabutylammonium peroxydisulfate as a versatile reagent (25 mol%) at ambient temperature under solvent-free conditions. This protocol was applied to the synthesis of drug-like molecules
摘要 通过使用四丁基过二硫酸铵作为通用试剂(25 mol%),通过邻氨基芳基酮与多种 α-亚甲基酮的串联杂环化反应,开发了一种简便实用的合成多种功能化喹啉的方法。无溶剂条件下的环境温度。该方案应用于类药分子的合成,类药分子是生物碱喜树碱的关键中间体。图形概要
