The carbocupration reactions of heterosubstituted alkynes allow the regio- and stereoselective formation of vinyl organometallic species. N-Alkynylamides (ynamides) are particularly useful substrates for the highly regioselective carbocupration reaction, as they lead to the stereodefined formation of vinylcopper species geminated to the amide moiety. The latter species are involved in numerous synthetically useful transformations leading to valuable building blocks in organic synthesis. Here we describe in full the results of our studies related to the carbometallation reactions of N-alkynylamides.
杂原子取代的炔烃的碳基化反应可以选择性地形成乙烯有机金属物种。尤其是N-炔基酰胺(ynamides)是高度选择性的碳基化反应的有用底物,因为它们导致与酰胺基团相结合的立体定义的乙烯铜物种的形成。后者参与许多合成有用的转化,导致有机合成中有价值的构建块的形成。在这里,我们全面描述了与N-炔基酰胺相关的碳金属化反应的研究结果。
