Knoevenagel condensation–reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58–92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further
已经开发了一种单锅汉兹奇酯介导的Knoevenagel缩合还原反应,用于将各种取代的2,4-喹啉二醇和2,4-吡啶二醇与醛进行烷基化。该工艺操作简单,可扩展,并提供了非常有用的C-3烷基化喹啉和吡啶二醇,收率58-92%。烷基化产物可以转化为2,4-二卤代喹啉和吡啶底物以进一步官能化。
