Ring transformation of condensed dihydro‐<i>as</i>‐triazines

Abstract

Abstract The 2‐amino‐ as ‐triazino[6,5‐ c ]quinoline as well as 3‐aminopyrido[4,3‐ e ]‐ as ‐triazine had previously been synthetized by Berényi (1) and Benkó et al (2). In this paper, the ring transformation occuring in aqueous media of the dihydro intermediates and their salts, respectively appearing during the synthesis of 2‐substitutedamino‐ as ‐triazino[6,5‐ c ]quinolines, are reported.
