A CuI‐catalyzed reductive coupling of ketone‐derived N‐tosylhydrazones with amides is presented. Under the optimized conditions, an array of N‐tosylhydrazones derived from aryl–alkyl and diaryl ketones could couple effectively with a wide variety of (hetero)aryl as well as aliphatic amides to afford the N‐alkylated amides in high yields. The method represents the very few examples for reliably accessing
本文介绍了CuI催化的酮基N-甲苯磺酰with与酰胺的还原偶联。在最佳条件下,衍生自芳基烷基和二芳基酮的一系列N-甲苯磺酰could可以与多种(杂)芳基以及脂肪族酰胺有效偶联,从而以高收率获得N-烷基化酰胺。该方法代表了通过还原性N烷基化方案可靠地获得仲和叔酰胺的例子。
