effective organocatalysts for the asymmetric Friedel–Craftsalkylation of indoles with 3-hydroxyisoindolin-1-ones. The corresponding products were obtained in excellent chemical yields (up to 99 %) with moderate to excellent enantioselectivities (up to >99 % ee after a single recrystallization). This is the first example of the catalytic asymmetric synthesis of valuable 3-substituted isoindolin-1-ones
