With 2-methyl-1,2,3,4-tetrahydroquinoline-derived phosphoramidite ligand (R,R(a))-L(6), Ir-catalyzed intramolecular C-3 allylic alkylation of indoles has been realized to afford highly enantioenriched spiroindolenine derivatives in 92-98% yields with up to >99/1 dr and 97% ee.
(R,R(a))-L(6) 是一种基于 2-甲基-1,2,3,4-四氢喹啉的手性磷酰胺配体，通过铱催化吲哚的 C-3 位烯丙基内酰胺化反应，以高达 92-98%的收率、>99/1 的 dr 值和 97%的对映选择性得到了高度对映富集的螺吲哚啉衍生物。
