A novel K2S2O8-promoted oxidative cyclization of enamines is described. A variety of enamines having diverse functional groups and substitution patterns react well using K2S2O8 as the oxidant in the absence of catalyst. This protocol provides a very simple route for the synthesis of polycarbonyl pyrroles and has the advantages of readily available starting materials, mild reaction conditions, and a
描述了新的由K 2 S 2 O 8促进的烯胺的氧化环化。在不存在催化剂的情况下,使用K 2 S 2 O 8作为氧化剂,具有不同官能团和取代方式的多种烯胺反应良好。该方案为聚羰基吡咯的合成提供了非常简单的途径,并具有易于获得的起始原料,温和的反应条件和广泛的底物的优点。
