seven and eight membered rings were formed from cyclopentanone and cyclo-hexanone via cycloadditions of pyrrolidine enamines with alkynyl phosphonates. This procedure provides straightforward access to functionalized medium sized rings that could be further manipulated in the synthesis of a number of natural products.
通过吡咯烷烯胺与炔基膦酸酯的环加成反应,由环戊酮和环己酮形成七个和八个员环。该程序提供了对功能化中型环的直接访问,可以在合成多种天然产物时对其进行进一步操作。
