Atroposelective synthesis of axially chiral naphthylpyrroles by a catalytic asymmetric 1,3-dipolar cycloaddition/aromatization sequence [PDF]

A straightforward methodology for the enantioselective preparation of axially chiral 2-naphthylpyrroles has been developed. This protocol is based on a CuI/Fesulphos-catalyzed highly enantioselective 1,3-dipolar cycloaddition of an azomethine ylide ...
