Ba black sheep: We have developed novel barium/binol catalysts prepared from alkaline earth metal amides and chiral binaphthol ligands. These catalysts effectively promoted the asymmetric Friedel–Crafts–typealkylationreactions of indoles with chalconederivatives. This is the first example of asymmetric Friedel–Crafts–typealkylationreactionsusingchiral Brønsted bases.
