and diastereoselective functionalization of the secondary over the tertiary α-C–H bond of 2-substituted pyrrolidines is first realized. Subsequent intermolecular addition of a nucleophile to the generated N,O-acetal and cleavage of the aromatic substituent leads to 2,5-disubstituted pyrrolidines.
                                    通过使用邻苯醌作为内部氧化剂,首先实现了2-取代
吡咯烷的叔α-C–H键上的仲位的区域和非对映选择性官能化。随后将亲核剂分子间加成到所产生的N,O-
乙缩醛上并裂解芳族取代基,得到2,5-二取代的
吡咯烷。
