cycloaddition reaction for conversion of α-heteroatom-substituted exocyclic imines to C4 heterocyclic spiro-β-lactams has rarely been investigated due to their instability. Herein, we describe the Staudinger reaction between ketenes and α-selenium-substituted exocyclic imines to synthesize C4 spiro-β-lactams.
施陶丁格 烯酮-亚胺[2 + 2]环加成反应可将α-杂原子取代的环亚胺转化为C4杂环螺-β-内酰胺类化合物,因为其不稳定,因此很少进行研究。在本文中,我们描述了烯酮与α-硒取代的环外亚胺之间的Staudinger反应,以合成C4螺-β-内酰胺。
