Comparative study of the different approaches to the synthesis of isatins with a chiral substituent at the nitrogen atom

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Through a comparative study of three different routes to the synthesis of isatins with a chiral substituent on the nitrogen atom it has been shown that better results for preparing the isatins are achieved using the Sandmeyer (>99% ee, yield 50%) rather than the Stolle method (95% ee, yield 16%). The procedure proposed by Gassman for preparing isatins was unsuitable for the compounds described.
