decarbalkoxylations of disubstituted geminal diesters by water–DMSO with added salts (KCN or NaCN) is a convenient preparative route leading to the corresponding monoesters. Herein, we described an efficient and very simple methodology for the preparation of 2-(ethylsulfanyl)aniline derivatives through the unexpected ring opening of the corresponding N-substituted-2(3H)-benzothiazolones in the presence of disubstituted
水-DMSO加盐(KCN或NaCN)对双取代双酯二酯的脱碳烷氧基化反应是制备相应单酯的便捷制备途径。在此,我们描述了一种有效且非常简单的方法,可在双取代双键二酯KCN存在的情况下,通过相应的N-取代-2(3 H)-苯并噻唑酮的意外开环来制备2-(乙基硫烷基)苯胺衍生物。和水– DMSO。
