rhodium-catalyzed reaction of triazoles with acyl selenides. Under thermal reaction conditions and in the presence of a rhodium catalyst, a rapid 1,3-difunctionalization reaction occurs to provide valuable α-seleno enamides with high stereoselectivity and broad functional group tolerance, which was demonstrated in 35 examples with up to 95% yield. Computational calculations suggest a reaction pathway that
在此,我们报告了三唑与酰基硒化物的铑催化反应。在热反应条件和铑催化剂的存在下,发生快速的 1,3-双官能化反应以提供有价值的具有高立体选择性和广泛官能团耐受性的 α-硒代烯酰胺,这在 35 个实施例中得到了证明,产率高达 95% . 计算计算表明一种反应途径可以直接访问 1,3-双官能化,而不会间歇性地形成叶立德中间体。
