For the first time, a general catalytic procedure for the cross-coupling of primary amides and alkylboronic acids is demonstrated. The key to the success of this reaction was the identification of a mild base (NaOSiMe3) and oxidant (di-tert-butyl peroxide) to promote the copper-catalyzed reaction in high yield. This transformation provides a facile, high-yielding method for the monoalkylation of amides
首次展示了伯酰胺和烷基硼酸交叉偶联的通用催化程序。该反应成功的关键是确定了弱碱(NaOSiMe 3)和氧化剂(二叔丁基过氧化物)以促进铜催化反应的高产率。这种转化为酰胺的单烷基化提供了一种简便、高产的方法。
