Ethyl (E)-4,5-dibromo-2-pentenoate readily reacts with an assortment of primary amines in the presence of DBU to afford the corresponding conjugated aziridines in good to moderate yields. That the reaction is compatible with a nucleoside-derived amine suggests a broad scope of application. (C) 2004 Elsevier Ltd. All rights reserved.
