Reactions with unstable and highly reactive zwitterionic intermediates generated in transition-metal-catalysed processes provide new opportunities for molecular constructions. Here imines, activated by chiral organocatalysts, have been employed to trap the zwitterionic intermediates to give polyfunctionalized indole and oxindole derivatives in a single step with excellent diastereoselectivity and enantioselectivity.
