An efficient and practical strategy for the synthesis of highly functionalized racemic and non-racemic 4,5-dihydropyrroles via dominoring-opening cyclization (DROC) of activated aziridines with malononitrile in excellent yield and stereoselectivity is described. The reaction serves as a tool for the synthesis of a large variety of substituted 4,5-dihydropyrroles in enantiomerically pure forms.
