3-Acetyl-2-aminotropone (1a) reacted with hydrazine to afford its hydrazone (3a) and 3-methyl-1,8-dihydrocycloheptapyrazol-8-one (4), while methylamino- and pyrrolidinyl-substituted compounds 1b and 1c gave only the cyclized compound (4).Reactions of 2-acetyl-7-aminotropones 2a-d gave their hydrazones 5a-d and the hydrazone 6.The hydrazones 3a and 5b were heated in acetic acid to give 4 and 3-methyl-8-methylamino-1,2-diazaazulene (7), respectively.Several reactions of 4 and 6 were also described.
