4-Hydroxyquinolinone esters are a common motif for many medicinal agents. Several methods exist for preparation of these compounds, generally involving the use of sodium hydride, which raises significant safety issues and limits their application to large-scale synthesis. In this note a practical, safe, and general method that employs a combination of diisopropylethylamine and sodium tert-butoxide
4-羟基喹啉酮酯是许多药物的常见基序。存在几种制备这些化合物的方法,通常涉及氢化钠的使用,这引起了显着的安全性问题并且限制了它们在大规模合成中的应用。在此说明中,描述了一种实用,安全且通用的方法,该方法采用了二异丙基乙胺和叔丁醇钠的组合。这允许以良好的产率合成4-羟基喹啉酮酯和酰胺。
