α,β-Unsaturated γ-lactams undergo regio- and stereoselective 1,3-dipolar cycloadditions with N-benzyl and N-methyl nitrones and can act as acceptors in conjugate addition of N-methylhydroxylamine. These reactions give access to highly functionalized pyrrolidones.
α,β-不饱和γ-内酰胺与N-苄基和N-甲基硝酮进行区域和立体选择性的1,3-偶极环加成反应,并且可以在N-甲基羟胺的共轭加成中充当受体。这些反应使获得高度官能化的吡咯烷酮成为可能。
