  Preparation of C-arylglycals via Suzuki–Miyaura cross-coupling of dihydropyranylphosphates

  摘要：

  The preparation of C-arylglycals has been accomplished by employing the Suzuki-Miyaura cross-coupling reaction of dihydropyranylphosphates with arylboronate esters. The reaction is tolerant of both electron-donating (EDG) and electron-withdrawing (EWG) groups on the aromatic ring and affords the corresponding C-arylglycals in good to excellent yields (68-97%). Additionally, the ketene acetal phosphate derived from 6-deoxy-3,4-di-O-benzyl-L-rhamnal also couples efficiently to yield C-arylglycals in excellent yields. (C) 2013 Elsevier Ltd.

  The Suzuki–Miyaura cross-coupling reaction of cyclic ketene acetal phosphates with arylboronic acids was found to be a convenient and highly efficient method for the construction of aryl vinyl ethers. A wide variety of differentially substituted electron-poor and electron-rich arylboronic acids smoothly underwent the coupling process to provide the desired dihydropyrans in moderate to excellent yields

  环状烯酮缩醛磷酸酯与芳基硼酸的Suzuki-Miyaura交叉偶联反应被发现是构建芳基乙烯基醚的一种方便而高效的方法。各种各样的差异取代的贫电子和富电子芳基硼酸顺利地进行了偶联过程，以中等至极好的收率提供了所需的二氢吡喃。
