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.
