Double Axially Chiral Bisphosphorylimides Catalyzed Highly Enantioselective and Efficient Friedel-Crafts Reaction of Indoles with Imines

Cool cats: 1,1′‐Bi‐2‐naphthol and vaulted 3,3′‐biphenanthrol‐type bisphosphorylimides enabled the atom‐economical and highly enantioselective Friedel–Crafts reaction between indoles and N‐tosylimines with a low catalyst loading (see scheme). A very small amount of 4‐(dimethylamino)pyridine (DMAP) su...

Description
Summary:Cool cats: 1,1′‐Bi‐2‐naphthol and vaulted 3,3′‐biphenanthrol‐type bisphosphorylimides enabled the atom‐economical and highly enantioselective Friedel–Crafts reaction between indoles and N‐tosylimines with a low catalyst loading (see scheme). A very small amount of 4‐(dimethylamino)pyridine (DMAP) suppressed the bisindole side product efficiently. The ortho‐substituted aldimine substrates performed excellently in this catalytic system.
