The Ivanov magnesium reagents obtained from aryl-acetic acids add to 3,3-dimethyl-2-phenyl azirine to give β-aziridino acids 4, which are easily transformed into 4-amino lactones 10 and further into butenolides 11. If sodium is substituted for magnesium the reaction takes a different course leading to pyrrolinones 8. The interaction between the deprotonated amino and carboxyl functions leading to an
由芳基乙酸制得的Ivanov镁试剂加到3,3-二甲基-2-苯基叠氮基上,生成β-叠氮基酸4,它们很容易转化成4-氨基内酯10,进而转化成丁烯内酯11。如果用钠代替镁,则反应会采取不同的过程,从而导致吡咯烷酮8。值得注意的是,去质子化的氨基和羧基官能团之间会形成酰胺基团。同时形成同时取代的γ-氨基巴豆酸7E。
