Southwick reaction

As already mentioned, besides multistage reactions there are also synthetic methods for obtaining aziridinyl ketones from unsaturated carbonyl compounds without the need for initial modification. Among such methods, the Southwick reaction consisting of the interaction of unsaturated ketones... 

For example, Southwick and Christman [34] described obtaining trans-azir-idine 18 from chalcone 22 (Scheme 1.7). Reactions of 22 with cyclohexylamines and benzylamines forming the corresponding N-substituted derivatives are mentioned in the same publication. Zvonok et al. [35] studied the interaction of cyclohexylamine 9 with 6-phenyl-2,3-epoxyhex-5-en-4-ones 23, leading to compounds 24 (Scheme 1.7). 

C—H bond, in HO Ac the carboxymethyl radical. This type of reaction occurs by rate-determining enolization of the radical-producing species (de Klein, 1977 Southwick, 1970 van der Ploeg et al., 1968).
