S. Fioravanti et al., A facile synthesis of N-alkoxycarbonyl aziridines from olefins bearing twogeminal electron-withdrawing groups, SYNTHESIS-S, (13), 2001, pp. 1975-1978
Nosyloxycarbamates react with unsaturated beta -dicarbonyl compounds at roo
m temperature in the presence of calcium oxide to give N-alkoxycarbonyl azi
ridines in high yield.
