Herein, we report a practical method for accessing this class of compounds via photocatalyzed hydroarylation of azine-substituted enamides with the in situ-generated aryl thianthrenium salts as the radical precursor. This reaction features a broad substrate scope, good functional group tolerance, and mild conditions and is suitable for the late-stage installation of α-amino azines in complex structures
α-氨基吖嗪广泛存在于药物和配体中。在此,我们报告了一种实用的方法,该方法通过以原位生成的芳基硫鎓盐作为自由基前体,对吖嗪取代的烯酰胺进行光催化加氢芳基化来获得这类化合物。该反应具有底物范围广、官能团耐受性好、条件温和等特点,适用于复杂结构中α-氨基吖嗪的后期安装。
