Flow chemistry: A flow‐microreactor‐mediated synthesis of 1,2,3,4‐tetrahydroisoquinolines (THIQs) is reported (see scheme). Starting from a laterally lithiated aziridine, a tetrahydroisoquinoline lithiated at C4 was generated by thermally induced isomerization. Because the reaction temperature is a crucial parameter, the exquisite thermal control possible in a flow‐microreactor system allowed for fast
流动化学:1,2,3,4-四氢异喹啉(THIQs)的流动微反应器介导的合成(见方案)。从侧面锂化的氮丙啶开始,通过热诱导的异构化生成在C4处锂化的四氢异喹啉。由于反应温度是关键参数,因此在流动微反应器系统中可能进行精确的热控制,以实现功能化氮丙啶或THIQ的快速,有效和高度可重复的合成。
