Enantioselective Construction of Spiroindolenines by Ir-Catalyzed Allylic Alkylation Reactions
摘要:
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.
