Abstract

A Solvent-Free Amidation of Vinylogous Esters via Direct Aziridination. -A microwave-mediated aziridination of α,β-unsaturated ketones and esters through the decomposition of ethyl azidoformate is developed. When this reaction is applied to cyclic vinylogous esters like (VIII) or (X), N-functionalization at the α-position occurs. Based on NMR analysis, these amidation products appear to be formed from the desired aziridine. -(MCLAUGHLIN*, E. C.; SHRESTHA, A.; FLETCHER, M. H.; STEINAUER, N. S.; SHINN, M. K.; SHAHID, S.
