A novel synthesis of 2‐alkyl indoles that uses N‐aryl‐2‐aminopyrimidines and sulfoxonium ylides was developed. It is an efficient and mild method for the synthesis of 2‐alkyl indoles. environmentally friendly solvents, efficient alternative carbenoid precursors, and novel catalyst system were used to complete this reaction. Many different directing groups can be used in this process, and the reaction
开发了使用N-芳基-2-氨基嘧啶和亚砜基鎓盐合成2-烷基吲哚的新方法。这是合成2-烷基吲哚的一种高效温和的方法。使用环保溶剂,有效的替代类胡萝卜素前体和新型催化剂体系来完成该反应。在该过程中可以使用许多不同的导向基团,并且该反应可耐受多种官能团。我们相信,这种有效地生产具有多个手柄以进一步衍生的2-烷基吲哚的合成方法学,在合成和制药行业中具有巨大的应用潜力。
