treated with diazomethane, methyl iodide, dimethyl sulfate, and diethyl sulfate to give 1- and 2-alkylated compounds. The 1,8-dihydrocycloheptapyrazol-8-one (2a) also reacted with 2-(dimethylamino)ethyl, 2-(diethylamino)ethyl, 3-(dimethylamino)propyl, and 2,3-dihydroxypropyl chloride to afford the corresponding 1-substituted products. A preliminary study was made of the biological activities of some of
用重氮甲烷,碘甲烷,硫酸二甲酯和硫酸二乙酯处理由3-乙酰基对苯二酚(1a-c)制得的3-甲基-1,8-二氢环庚基吡唑-8-酮(2a-c) -烷基化的化合物。1,8-二氢环庚吡唑-8-(2a)也与2-(二甲基氨基)乙基,2-(二乙基氨基)乙基,3-(二甲基氨基)丙基和2,3-二羟基丙基氯反应,得到相应的1-替代产品。对某些所得化合物的生物活性进行了初步研究。
