Abstract A microwave-mediated aziridination of α, β-unsaturated ketones and esters through the decomposition of ethyl azidoformate has been developed. When the same atom- economical reaction conditions are applied to cyclic vinylogous esters, N-functionalization at the α-position occurs. Based on NMR analysis, these amidation products appear to be formed from the desired aziridine in moderate to good yields.
