A new indium(III)‐catalyzed reaction for the synthesis of a series of indolizine scaffolds has been developed. This methodology was highly efficient, allowing a low catalyst loading of 2 mol % (down to 0.5 mol %) and rendering the products in high yields through a 5‐exo‐dig aza‐Conia‐ene reaction. Furthermore, the possibility of incorporating an electrophile into the generated pyrrolidone ring in a
已经开发了一种新的铟(III)催化反应,用于合成一系列吲哚嗪骨架。这种方法是高效率的,使2摩尔%的低催化剂负载(降到0.5摩尔%),并通过5-渲染以高收率产品外切-挖氮杂Conia烯反应。此外,还证明了以单锅协同方式将亲电试剂掺入生成的吡咯烷酮环中的可能性。最后,基于实验观察,提出了一种机制建议。
