Stereodivergent synthesis of 2,5-disubstituted pyrrolidines was achieved via a Au-catalyzed tandem intramolecular alkyne hydroamination/iminium formation/Et3SiH reduction. Importantly, the stereochemical outcome could be switched by choosing an appropriate nitrogen protecting group. Total synthesis of a diastereomeric pair of alkaloid natural products, monomorine I and indolizidine 195B, was achieved
2,5-二取代吡咯烷的立体发散合成是通过Au催化的串联分子内炔氢胺化/亚胺形成/Et 3 SiH还原实现的。重要的是,可以通过选择合适的氮保护基团来改变立体化学结果。生物碱天然产物 monomorine I 和 indolizidine 195B 的非对映体对的全合成,展示了串联反应的合成效用。
