We have prepared a library of functionalized quinolines through the magnesiation of 7-chloroquinolines under mild conditions, employing both batch and continuous flow conditions. The preparation involved the generation of mixed lithium-magnesium intermediates, which were reacted with different electrophiles. Mixed lithium-zinc reagents allowed the synthesis of halogenated and arylated derivatives. Some
我们已经在温和条件下通过 7-氯喹啉的氧化制备了功能化喹啉库,采用间歇和连续流动条件。制备涉及混合锂镁中间体的产生,这些中间体与不同的亲电试剂反应。混合锂锌试剂允许合成卤化和芳基化衍生物。一些合成的 4-甲醇喹啉显示出有趣的抗增殖特性,它们的羟基是合适的氨基生物电子等排体。我们还报告了光学活性衍生物的两步法。
