A Cu-catalyzed allyl−aryl coupling reaction between (Z)-acyclic or cyclic allylic phosphates and arylboronates proceeds with excellent γ-E-selectivity and 1,3-anti chirality transfer, which gives the corresponding coupling products with benzylic and allylic stereogenic centers. The wide availability and easy-to-handle nature of arylboronates, the inexpensiveness of the Cu catalyst system, and the high
(Z)-无环或环状烯丙基磷酸酯与芳基硼酸酯之间的Cu催化的烯丙基-芳基偶联反应具有出色的γ-E-选择性和1,3-抗手性转移,从而产生了具有苄基和烯丙基立体异构中心的相应偶联产物。芳基硼酸酯的广泛可用性和易于处理的性质,Cu催化剂体系的廉价以及高区域选择性和立体选择性是该方案的吸引人的特征。
