  锰催化的伯醇与2-芳基乙醇的双脱氧偶联

  摘要：

  本文报道了由定义明确的Mn / PNP夹杂物催化的伯醇与2-芳基乙醇的一般有效的双脱氧偶联反应。该反应是使用非贵金属催化剂对醇进行催化双脱氧的第一个例子。2-芳基乙醇的脱氧均偶联作用（17个实例）和它们与其他伯醇的脱氧交叉偶联（20个实例）均通过脱氢和甲酰基化反应顺序顺利进行，形成了相应的烯烃。

  Palladium-catalyzed selective Heck-type diarylation of allylic esters with aryl halides has been developed. Allylic esters are reacted with aryl iodides to provide the corresponding 1,3-diaryl propenes through a β-OAc elimination process. It is noteworthy that the methodology can be applied in constructing the indole and benzofuran skeletons.

  已经开发了钯催化的烯丙基酯与芳基卤化物的选择性Heck型二芳基化。使烯丙酸酯与芳基碘化物通过β-OAc消除过程提供相应的1，3-二芳基丙烯。值得注意的是，该方法可用于构建吲哚和苯并呋喃的骨架。
