A modification of the Gassman oxindole synthesis is described that proceeds from anilines and ethyl (methylsulfinyl)acetate, using oxalyl chloride to activate the sulfoxide to facilitate the formation of the key N - S bonded intermediate. This procedure is particularly convenient for reactions carried out on smaller scales and for anilines that are susceptible to electrophilic halogenation.
描述了Gassman oxindole合成方法的一种改进方法,该方法是从苯胺和(甲基亚磺酰基)乙酸乙酯开始,使用草酰氯激活亚砜以促进键合的N-S键合中间体的形成。对于小规模进行的反应和易受亲电子卤化作用的苯胺,此程序特别方便。
