Under selected conditions, the Zr-catalyzed reaction of EtMgCl with imines produces C,N-dimagnesiated compounds, which can be further trapped with electrophiles. The overall transformation provides a new route to bifunctional or cyclic nitrogen-containing compounds. Particularly, 1-azaspirocyclic γ-lactams, pyrrolidines and azetidines can be obtained in this way.
在选定的条件下,Zr 催化 EtMgCl 与
亚胺的反应可生成 C,N-二
镁离子化合物,这些化合物可进一步与亲电体发生反应。整个转化过程为获得双官能团或环状
含氮化合物提供了一条新途径。特别是可以通过这种方法获得 1-氮杂环δ-内酰胺、
吡咯烷和氮杂
环丁烷。
