regio- and diastereoselective cyclization/hydroarylation reaction of 1,5- and 1,6-dienes with aromatic ethers and tertiary anilines was established by a cationic 2-picoline-tethered-half-sandwich scandium alkyl catalyst, which constitutes a process for producing a diverse array of cis-1,3-disubstituted arylated and trans-1,2-disubstituted benzylated methylcyclopentane derivatives in one step with 100% atom-efficiency
1,5-和1,6-二烯与芳族醚和叔苯胺的高度区域和非对映选择性环化/氢芳基化反应是通过阳离子2-甲基吡啶系留的半三明治s烷基烷基催化剂建立的,一步以100%的原子效率生产多种顺式-1,3-二取代的芳基化和反式-1,2-二取代的苄基化甲基环戊烷衍生物。此外,还提出了涉及involving催化的芳族邻-C-H活化和烯烃插入级联反应的机理。
