A copper catalyzed three-component reaction was developed for the synthesis of benzothiazolones. In the presence of CuBr2, the reaction of o-iodoanilines and K2S with DMF proceeded smoothly and generated the corresponding benzothiazolones with good isolated yields. DMF functioned both as the carbon monoxide source and as the reaction medium in this reaction.
开发了一种铜催化的三组分反应,用于合成苯并噻唑酮。在CuBr2的存在下,o-碘苯胺和K2S与DMF的反应顺利进行,生成了相应的苯并噻唑酮,收率良好。DMF在该反应中既作为一氧化碳源,又作为反应介质。
