The first direct enantioselective Friedel–Crafts reaction of indoles with isatins has been developed. The process is catalyzed by simple cupreine under mild reaction conditions and affords synthetically and biologically interesting, chiral 3‐indolyl‐3‐hydroxy‐2‐oxindoles in good yields (68–97%) and with high enantioselectivities (76–91%).
已经开发了吲哚与靛红的第一个直接对映选择性的弗瑞德-克来福特反应。该过程在温和的反应条件下由简单的铜胺催化,可提供合成和生物学上有趣的手性3-吲哚基-3-羟基-2-氧吲哚,产率高(68-97%),对映选择性高(76-91%)。
