directing group: The C7 position of the indoline nucleus is difficult to address in CH activation. An oxidative palladium(II) catalysis that allows for cross‐dehydrogenative coupling in that position with activation of the CH bond of the arene component is disclosed here. This CH/CH cross‐coupling is applicable to various indolines acetylated at the nitrogen atom. Substitution at C2 is crucial for
指导小组:吲哚核的C7位置很难通过CH激活来解决。本文公开了一种氧化钯(II)催化,该催化作用允许在该位置进行交叉脱氢偶联并激活芳烃组分的CH键。这种CH / CH交叉偶联适用于在氮原子上乙酰化的各种二氢吲哚。取代在C2是用于C关键 ħ激活在C7发生(参见方案)。
