The title compound I was transformed to its oxime II, hydrazone III and semicarbazone IV. 1-(4-Methylsulfonylphenyl)-2-(4-phenylpiperazino)ethanol (V) was esterified by the corresponding acid chlorides in pyridine to give the acetate VI, propionate VII, benzoate VIII, and 4-nitrobenzoate IX. Reactions of 4-(methylsulfonyl)phenacyl bromide, its 4-(ethylsulfonyl), and 4-(2-methylpropylsulfonyl)analogues with diethanolamine afforded instead of the expected substitution products X the hemiacetals XI-XIII, i.e. 2-hydroxy-4-(2-hydroxyethyl)-2-(4-alkylsulfonylphenyl)morpholines. The products were subjected to the pharmacological and microbiological screening; compounds II-IV and VI-IX have more or less the character of tranquillizers, the hemiacetals XI-XIII have some antimicrobial activity in vitro. Compound XIII showed, surprisingly, a positively inotropic effect, and its methiodide XIV a peripheral myorelaxant effect.
标题化合物 I 转化为其肟 II、腙 III 和半卡巴zone IV。1-(4-甲基磺酰基苯基)-2-(4-苯基哌嗪基)乙醇 (V) 通过相应的酸氯化物在吡啶中酯化,得到乙酸酯 VI、丙酸酯 VII、苯甲酸酯 VIII 和4-硝基苯甲酸酯 IX。4-(甲磺酰基)苯乙酰溴及其4-(乙磺酰基)和4-(2-甲基丙磺酰基)类似物与二乙醇胺反应,得到预期的取代产物 X 的半缩醛 XI-XIII,即2-羟基-4-(2-羟乙基)-2-(4-烷基磺酰基苯基)吗啡啶。产物经药理和微生物学筛选;化合物 II-IV 和 VI-IX 具有镇静剂的特性,半缩醛 XI-XIII 在体外具有一定的抗微生物活性。化合物 XIII 显示出惊人的正性肌力作用,其甲碘化物 XIV 具有外周肌松效应。
