Reaction of 1,2-dialkyldiaziridines with ketenes as a new approach to cyclic and linear systems containing the N-C-N fragment

Shevtsov,Petukhova,Strelenko,Lyssenko,Makhova,Tartakovsky

, p. 1021 - 1031 (2005)

The reaction of 1,2-dialkyldiaziridines with ketenes proceeds through the N-N bond cleavage to form three types of structures containing the N-C-N fragment, viz., 1,3-dialkylimidazolidin-4-ones, 3,5-diacyl-3,5-diazahept-1-enes, and β-lactams. The reaction
