The iron(II) chloride- and copper(I) iodide-mediated carbozincation of a panel of substituted ynamides is described in this article. The reaction is totally regio- and stereoselective. Experiments showed that the reaction mediated with Fe(II) was more substrate dependent than the reaction performed with Cu(I). Interestingly, in the presence of allylbromide, stereoselective carboallylation can be achieved
本文描述了一组取代的乙酰胺的氯化铁(II)和碘化铜(I)介导的碳氧合。该反应是完全区域和立体选择性的。实验表明,Fe(II)介导的反应比Cu(I)进行的反应对底物的依赖性更大。有趣的是,在存在烯丙溴化物的情况下,可以第一次在单锅法中实现立体选择性碳烯丙基化,导致跳过二烯酰胺。
