3-Substituted 5-nitrosotropolone (IIIa∼c), 7H-cyclohepta [b] pyrazin-7-one oxime (VIIIa, b), 8H-cyclohepta [b] quinoxalin-8-one oxime (IXa∼c), 9H-cyclohepta [b] naphtho [2, 3-e] pyrazin-9-one oxime (X), 5-nitrosotropolone guanidine adduct (XI), 2-(2-acetylhydrazino)-5-nitrosotropone (XII and its analogues) and 2-(2-troponylhydrazino)-5-nitrosotropone (XIV) were synthesized according to the schemes shown in Chart 1, 2, and 3. In addition, some reactions related to IIIa and IIIc were described. Among these derivatives, 2-(2-isonicotinoylhydrazino)-5-nitrosotropone and its N-oxide showed remarkable anti-tumor activities on ascitic and solid forms of Ehrlich tumor and Sarcoma 180.
