investigated, utilizing readily available primary alcohols as acylating sources. Overall, this oxidative coupling proceeds via three distinct transformations such as oxidation, radical formation, and cross-coupling in one catalytic process. This protocol does not involve the assistance of a directing group or activation of the carbonyl group by any other means. Furthermore, this reaction made use of no
在本研究中,利用容易获得的伯醇作为酰化源,研究了通过交叉脱氢偶联进行钯催化的直接氧化酰化。总体而言,这种氧化偶联通过三种不同的转化进行,例如氧化、自由基形成和一个催化过程中的交叉偶联。该协议不涉及导向基团的协助或通过任何其他方式激活羰基。此外,该反应没有使用有毒的一氧化碳气体作为羰基化剂;相反,原料伯醇已被用作酰化源。值得注意的是,可以合成苯并呋喃酮和茚酮。该策略也适用于正丁基苯酞、非诺贝特、吡托苯酮和新木脂素的合成。
