The installation of sulfonamide pharmacophores on heterobiaryls has successfully been executed by a previously unknown palladium-catalyzed intramolecular oxidative coupling in N-arylsulfonyl heterocycles followed by novel ring opening of heterobiaryl sultams with amine nucleophiles. The protocol has a wide scope of substrates warranting broad applications in the synthesis of heterobiaryls containing
磺酰胺药效基团在杂二芳基化合物上的安装已成功地通过在N-芳基磺酰基杂环中进行
钯催化的分子内氧化偶合反应完成,随后通过
胺类亲核试剂实现了杂二芳基磺
胺类化合物的新型开环。该方案具有广泛的底物范围,可确保在合成含邻磺酰基或羧基官能团的杂二芳基化合物中具有广泛的应用。
