An unusual NaH-mediated remote anionic 1,5-thia-Fries rearrangement reaction was developed. This method provides an efficient approach for the regioselective synthesis of not only 2-(2-hydroxyphenyl)-3-indole triflones but also related 3-sulfonylindoles.
开发了一种异常的NaH介导的远程阴离子1,5-硫代-弗里斯重排反应。该方法不仅为2-(2-羟苯基)-3-吲哚三氟酮而且还为相关的3-磺酰吲哚的区域选择性合成提供了一种有效的方法。
