A synthetic approach to dihydropyrrolizine and tetrahydroindolizine scaffolds from pyrroles has been developed. The key step, a titanocene(III)‐catalyzed radical arylation that proceeds by C−H functionalization is atom‐economical and tolerates a large variety of functional groups. The reaction is therefore attractive for the swift assembly of functional and structural diversity.
已经开发了从吡咯合成二氢吡咯烷嗪和四氢吲哚嗪支架的方法。关键步骤是通过C–H官能化进行的钛茂(III)催化的自由基芳基化是原子经济的,并且可以耐受多种官能团。因此,该反应对于快速组装功能和结构多样性具有吸引力。
