Reaction of primary amines on α-ethoxycarbonyl hydrazonates
Written by sctunisie no commentsα-carboethoxyhydrazones 1 react with orthoesters to give α-carboethoxyhydrazonates 2. Treatment of these hydrazonates with primary amines yields to α-amidohydrazonates 3 (when the amines are aliphatics) and to 4,5-dihydro-1.2.4 triazin-5-ones 4 (aromatic amines).
