Controllable β-carbon elimination to extrude norbornene remains a long-standing challenge in palladium and norbornene chemistry. Herein, this manuscript describes a switchable synthesis of biologically active C4-ethylaminoindole and C7-aminoindoline scaffolds by controlling β-carbon elimination, utilizing aziridine as a C-H ethylamination reagent through a C-N bond cleavage reaction. Furthermore, the protecting groups of the product can be easily removed, offering an unusual method for the synthesis of dopamine receptor agonists.
在钯和降冰片烯化学领域，可控的β-碳消除以挤出降冰片烯仍是一个长期存在的挑战。本文描述了一种通过控制β-碳消除，以氮丙啶作为C-H乙基化试剂，通过C-N键裂解反应，可切换合成生物活性C4-乙基氨基吲哚和C7-氨基吲哚啉支架的方法。此外，产物的保护基团可轻松去除，为多巴胺受体激动剂的合成提供了一种独特的方法。
