Studies of the chemistry of heterocycles

In contrast to arylamides of N-benziloyl-p-aminobenzoic acid, the acidochromic cyclization of arylamides of N-benziloylanthranilic acid is accompanied by deamination and, regardless of the nature of the arylamide group, leads to the formation of 7-carboxy-3,3-diphenyl-2-k etoindoline.See [1] for communication LII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 182–183, February, 1972.
