The reactions of 3-acetyltropolone and 3-acetyl-2-methoxytropone with methylhydrazine gave 1,3-dimethyl-1,8-dihydrocycloheptapyrazol-8-one (3) and 2,3-dimethyl-2,8-dihydrocycloheptapyrazol-8-one. 7-Acetyl-2-methoxytropone reacted with methylhydrazine to afford 1,3-dimethyl-1,8-dihydrocycloheptapyrazol-8-one methylhydrazone, besides a small amount of 3.
3-乙酰基托罗烯和3-乙酰基-2-甲氧基托罗烯与甲基肼的反应生成了1,3-二甲基-1,8-二氢环七吡唑-8-酮(3)和2,3-二甲基-2,8-二氢环七吡唑-8-酮。7-乙酰基-2-甲氧基托罗烯与甲基肼反应,除了生成少量的3,还得到了1,3-二甲基-1,8-二氢环七吡唑-8-酮甲基肼素。
