CuI/phosphoramidite‐catalyzed asymmetric allylic alkylation of allyl ethers with organolithiumreagents is reported (see scheme). The use of organolithiumreagents is essential for this catalytic CC bond formation due to their compatibility with different Lewis acids. The versatility of allylic ethers under the copper‐catalyzed reaction conditions with organolithiumreagents is demonstrated in the shortest
报道了用有机锂试剂对烯丙基醚进行的高效,区域和对映选择性的Cu I /亚磷酰胺催化的不对称烯丙基烷基化反应(参见方案)。由于与不同的路易斯酸具有相容性,因此使用有机锂试剂对于这种催化的CC键形成至关重要。(S)-戊二酸的最短合成证明了烯丙基醚在铜催化的条件下与有机锂试剂的多功能性。
