Variations on a theme: A mild and general intramolecular copper‐mediated carbomagnesiation procedure for the synthesis of functionalized indoles as well as 4‐, 5‐, 6‐, and 7‐azaindoles starts from readily available ynamides. Subsequent reactions with various electrophiles provides polyfunctional N‐heterocycles in good yields.
一个主题的不同之处:用于合成功能化的吲哚以及4、5、6和7氮杂吲哚的温和且一般的分子内铜介导的碳镁还原过程是从容易获得的乙酰胺开始的。随后与各种亲电试剂的反应可提供高收率的多官能N杂环。
