  通过 1,3-卤素迁移铜催化回收卤素活化基团

  摘要：

  Cu(I) 催化的 1,3-卤素迁移反应通过将溴或碘从 sp(2) 转移到苄基碳并伴随 Ar-X 键的硼化，有效地回收了活化基团。所得苄基卤可以在同一容器中在各种条件下反应以形成额外的碳-杂原子键。使用同位素富集的溴化物源的交叉实验支持 Br 的分子内转移。假设该反应通过邻卤苯乙烯的马尔科夫尼科夫氢铜反应、所得 Cu(I) 络合物氧化加成到 Ar-X 键中、还原消除新的 sp(3) CX 键和最终硼化反应进行Ar-Cu(I) 物种翻转催化循环。

  A Cu(I)-catalyzed 1,3-halogen migration reaction effectively recycles an activating group by transferring a halogen from an sp 2 to a benzylic carbon with good enantioselectivity and concomitant borylation of the Ar-halo bond. The resulting enantio-enriched benzyl halide can be reacted in the same vessel under a variety of conditions to form an additional carbon-heteroatom or carbon-carbon bond while maintaining high ee. The reaction can be used to efficiently prepare novel compounds and intermediates for the preparation of therapeutics and ligands for catalysis.
