to synthesize and apply allenol. However, limited efforts have been made to obtain a trifluoromethyl-substituted allenol. Here, by using a readily available 1,3-enyne as the starting material, a copper-catalyzed trifluoromethylbenzoxylation process was developed for efficient synthesis of trifluoromethyl-substituted allenols using Togni-II reagent as the reaction partner. Triple roles of the Togni-II
Allenol 已被确定为用于有机合成的多功能构建单元,并且已经做出了许多努力来合成和应用 Allenol。然而,为获得三氟甲基取代的丙二烯醇所做的努力有限。在这里,通过使用容易获得的 1,3-烯炔作为起始原料,开发了一种铜催化的三氟甲基苯甲酰化工艺,用于使用 Togni-II 试剂作为反应伙伴有效合成三氟甲基取代的丙二烯醇。在这种转化中阐明了 Togni-II 试剂的三重作用,包括作为三氟甲基的来源、羟基的来源和氧化剂。此外,还进行了后期多元化,
