资源简介：
We report herein an unprecedented direct catalytic C6 functionalization reaction of 2,3-disubstituted indoles with various N–Ts aziridines catalyzed by Sc(OTf)3 under mild conditions. Mechanistic studies revealed that a kinetically favored but reversible formal [3 + 2] annulation occurs initially. The direct C6 functionalization, although having a relatively higher energetic barrier, delivers the thermodynamically favorable products.
