use of a Ru photocatalyst and Umemoto’s reagent as a CF3 source is key in the present carbolactonization. This is the first example of a highly endo- and diastereoselective synthesis of CF3-substituted five-, six-, and seven-membered ring lactones from internal alkenoic acids.
                                    已经开发了通过光氧化还原催化的末端和内部链烷酸的三
氟甲基内酯化。Ru的光催化剂和
梅本试剂作为CF 3来源的使用是当前碳酰化的关键。这是从内部链烷酸高度内切和非对映选择性合成CF 3取代的五元,六元和七元环内酯的第一个例子。
