Abstract
The reaction of alpha,beta-unsaturated esters with (ethoxycarbonyl)nit rene, generated by alpha-elimination of NsONHCO(2)Et using CaO as a ba se in heterogeneous phase, allowed the preparation of aziridine-1,2-di carboxylates (2a-e) in good isolated yields (57-72%). The same reactio n does not take place using triethylamine instead of CaO, in homogeneo us conditions. Copyright (C) 1996 Elsevier Science Ltd
