The NH2 group serves as an effective leaving group in the palladium‐catalyzed regioselective and stereospecific title reaction (see scheme). The reaction works well with aryl‐ and alkenylboronic acids and aryl‐, alkenyl‐, allyl‐, and benzylboronates, and complete transfer of chirality has been achieved when using α‐chiral primary allylic amines as the allylic electrophiles.
NH 2 基团是钯催化的区域选择性和立体特异性标题反应中有效的离去基团(请参见方案)。该反应与芳基和烯基硼酸以及芳基,烯基,烯丙基和苄基硼酸酯反应良好,当使用α-手性伯烯丙基胺作为烯丙基亲电试剂时,已经实现了手性的完全转移。
