An efficient synthesis of oxindoles is achieved from a thermal and rhodium(II)-catalyzed Wolff rearrangement of diazoquinolinediones in moderate yields.
Cyclization and oxidation of o-bromophenylacetamides for the synthesis of oxindoles and isoindigoes
Liu, Liang,Song, Lei,Guo, Yujun,Min, Dewen,Shi, Tianchao,Zhang, Wu
, p. 354 - 359 (2017/12/26)
N-substituted oxindoles were obtained through a facile KOH/DMSO promoted intramolecular cyclization of o-bromophenylacetamides in good yields. Furthermore, isoindigo derivatives were readily synthesized through sequential intramolecular cyclization, oxida
