The regioselectivity of the cycloaddition of mesoionic oxazolones to alkenes has been found to be markedly dependent on the substituent groups present and an explanation is proposed.
Addition d'azlactones ylures d'azomethine potentiels a quelques alcenes electrophiles, en milieu anhydride acetique : obtention de pyrrolines-2 et de pyrroles N-acetyles

Azlactones, potential azomethin-ylids, are prepared in situ acetic anhydride from the corresponding α-amino acid, and their addition to electrophilic alkenes RCH=C(X)(Y) leads to N-acetyl Δ2-pyrroline.If X=Y=CN, the pyrroline eliminates HCN and produces a pyrrole.If R=H (acrylic and methacrylic esters and nitriles) the hydrolytic openchain products are obtained.
