N-Arylation of Isatins. A Direct Route to N-Arylisatoic Anhydrides
Coppola, Gary M.
, p. 1249 - 1251 (2007/10/02)
The synthesis of N-arylisatoic anhydrides 3 has been accomplished by using a two-step process.The key reaction in the sequence is the direct N-arylation of isatin with an aryl bromide in the presence of cupric oxide.Subsequent oxidation of the resulting N
