Asymmetric Synthesis of Indole Homo-Michael Adducts via Dynamic Kinetic Friedel–Crafts Alkylation with Cyclopropanes
摘要:
An enantioconvergent Friedel-Crafts alkylation of indoles with donor-acceptor cyclopropanes is described. The reaction is catalyzed by pybox center dot Mgl(2) and proceeds via a type I dynamic kinetic asymmetric transformation (DyKAT).
