readily available N-(2-pyridyl)anilines and commercially available α-Cl ketones through iridium-catalyzed C–H activation and cyclization is reported here. As a complementary approach to the conventional strategies for indole synthesis, the transformation exhibits powerful reactivity, tolerates a large number of functional groups, and proceeds with good to excellent yields under mild conditions, providing
此处报道了一种简便易行的方案,可通过铱催化的C–H活化和环化作用,从易于获得的N-(2-吡啶基)苯胺和市售的α-Cl酮合成2-芳基吲哚化合物。作为吲哚合成常规策略的一种补充方法,该转化反应显示出强大的反应活性,可以耐受大量的官能团,并且在温和的条件下以良好或优异的产率进行合成,为获得结构多样且有价值的吲哚支架提供了直接的方法。此外,反应可以容易地放大至克级。
