Oxidative palladium-catalyzed reaction conditions have been developed to allow for regioselective and stereoselective coupling of allylic boronic esters with a range of carbon-, oxygen-, and nitrogen-based nucleophiles. Studies into the mechanism of the reaction have shown that the key transmetalation step occurs with retention of stereochemistry, since overall inversion is observed.
已经开发出氧化钯催化的反应条件以允许烯丙基硼酸酯与一系列碳基、氧基和氮基亲核试剂的区域选择性和立体选择性偶联。对反应机理的研究表明,关键的金属转移步骤伴随着立体化学的保留而发生,因为观察到了整体反转。
