oxygen-mediated method for the selective hydroxyalkylation and alkylation of quinoxalin-2(1H)-ones with alkylboronic acids under transition-metal free conditions has been developed. This strategy demonstrates a broad scope of quinoxalin-2(1H)-ones and alkylboronic acids, giving 3-hydroxyalkylquinoxalin-2(1H)-ones and 3-alkylquinoxalin-2(1H)-ones in moderate-to-good yield. Control experiments reveal that
在此,开发了一种有效的分子氧介导的方法,用于在无过渡金属条件下用烷基硼酸选择性羟烷基化和烷基化 quinoxalin-2(1 H )-ones。该策略展示了广泛的 quinoxalin-2(1 H )-ones 和烷基硼酸,使 3-hydroxyalkylquinoxalin-2(1 H )-ones 和 3-alkylquinoxalin-2(1 H )-ones 处于中等至良好的屈服。对照实验表明涉及一种激进的途径。
