We report on a study of copper-catalyzed alkylation of internal allylic carbonates using functionalized alkyl and aryl Grignardreagents. The reactions exhibit good regioselectivity for either SN2 or SN2′ products, enabling the preparation of products with E-alkene selectivity. Density functional theory (DFT) calculations reveal the origins of the regioselectivity based on the different behaviors of
我们报告了使用官能化烷基和芳基格氏试剂铜催化内烯丙基碳酸酯烷基化的研究。该反应对S N 2 或S N 2' 产物表现出良好的区域选择性,使得能够制备具有E-烯烃选择性的产物。密度泛函理论(DFT)计算揭示了基于同铜酸盐和异铜酸盐的不同行为的区域选择性的起源。
