An enantioselective fluorination of 3‐functionalized oxindoles using electron‐rich amino urea catalyst is described. Various 3‐functionalized 3‐fluoro‐2‐oxindoles were obtained in good yields and enantio‐selectivity. The resulting enantioenriched 3‐methylene nitrile 3‐fluoro‐2‐oxindole product was found to inhibit indoleamine 2,3‐dioxygenase considerably.
描述了使用富电子氨基脲催化剂对3-官能化吲哚进行对映选择性氟化的方法。获得了各种3官能化的3-氟-2-氧吲哚,并具有良好的收率和对映选择性。发现所得的对映体富集的3-亚甲基腈3-氟-2-氧吲哚产物可显着抑制吲哚胺2,3-二加氧酶。
