A novel and efficient two-step synthetic sequence for the preparation of 3,3-disubstituted oxindoles was developed starting from arylhydrazines and α-branched aldehydes via Fischer indole type synthesis followed by imine oxidation.
从芳基肼和α-支化醛开始,通过Fischer吲哚型合成,然后进行亚胺氧化,开发了一种新颖且有效的两步合成序列,用于制备3,3-二取代的羟吲哚。
