A CuH‐catalyzed enantioselective hydroamidation reaction of vinylarenes has been developed using readily accessible 1,4,2‐dioxazol‐5‐ones as electrophilic amidating reagents. This method provides a straightforward and efficient approach to synthesize chiral amides in good yields with high levels of enantiopurity under mild conditions. Moreover, this transformation tolerates substrates bearing a broad
使用容易获得的1,4,2-二恶唑-5-酮作为亲电子酰胺化试剂,开发了CuH催化的乙烯基芳烃对映选择性加氢酰胺化反应。该方法提供了一种简单有效的方法,可以在温和条件下以高收率和高对映体纯度合成手性酰胺。而且,这种转变可耐受带有广泛官能团的底物。
