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
