Aziridinyl alkynes strike gold: A novel gold(I)‐catalyzed domino transformation of aziridinyl alkynes with arenes to construct 1,2,3,4‐tetrahydroisoquinoline and 3,4‐dihydroisoquinoline structural motifs (see scheme), especially sterically congested syn‐3,4‐disubstituted 1,2,3,4‐tetrahydroisoquinolines, is described. A plausible mechanism proceeding through a benzylic cation is given based upon deuterium‐labeling
氮丙啶基炔撞击金:一种新型的金(I)催化的氮丙啶基的炔烃的芳烃与多米诺转化构建1,2,3,4-四氢异喹和3,4-二氢异喹啉的结构基序(参见方案),特别是空间位阻的顺式-3描述了4,4-二取代的1,2,3,4-四氢异喹啉。根据氘标记和对照实验以及观察到的非对映选择性,给出了通过苄基阳离子进行的合理机理。
