with a variety of aryl zincates derived from lithium aryl n-butyl pinacol boronates and ZnBr2 under mild reaction conditions was described. In addition to mild reaction conditions, another advantage includes the compatibility of various common functional groups such as fluoride, chloride, bromide, cyano, or ester groups. Furthermore, this protocol was successfully applied to the enantioselective synthesis
描述了在温和的反应条件下,钴催化的α-溴-α-氟甲苯衍生物与各种衍生自芳基正丁基频哪醇硼酸锂和ZnBr 2的芳基锌酸酯的不对称交叉偶联。除了温和的反应条件外,另一个优势包括各种常见官能团(例如氟,氯,溴,氰基或酯基)的相容性。此外,该方案已成功应用于生物活性化合物或药物分子的三种氟化衍生物的对映选择性合成。
