We herein present a flexible approach for the incorporation of CF3 units into a predefined site of electron-rich alkenes that exploits the regiocontrolled introduction of an iodine handle and subsequent trifluoromethylation of the C(sp2)–I bond using fluoroform-derived “ligandless” CuCF3. The broad substrate scope and functional group tolerance together with the scalability and purity of the resulting
我们在此提出了一种将CF 3单元并入富含电子的烯烃的预定位点的灵活方法,该方法利用了碘控制的区域控制性引入以及随后使用氟仿衍生的“无配位体”对C(sp 2)-I键进行了三氟甲基化。” CuCF 3。广泛的底物范围和官能团耐受性以及所得产品的可扩展性和纯度使复杂的CF 3支架(如糖,核苷(抗病毒剂)和杂环(吲哚和色酮),具有学术和工业应用潜力。
