A new reaction of 1,2‐di‐ and 1,2,3‐trialkyldiaziridines: Ring expansion under the action of diethyl acetylenedicarboxylate in ionic liquids

Abstract

New reaction of diaziridine ring expansion resulting in diethyl 1,2,3,6-tetrahydropyrimidine-4,5-dicarboxylate derivatives was discovered under the action of diethyl acetylenedicarboxylate on 1,2-di-and 1,2,3-trialkyldiaziridines in ionic liquids.
