Abstract

original image

Two steps can be better than one: An efficient synthesis of enantioenriched N-allylindoles by a one-pot Ir-catalyzed asymmetric allylic alkylation/oxidation reaction of indolines has been realized. The current method features high regioselectivity and enantioselectivity together with a broad range of indoles with varying electronic properties. The utility of this method was demonstrated by the synthesis of dihydropyrrolo[1,2-a]indole derivatives.
