Reactions of 2-chloro- and 2-methyl-6,11-dihydrodibenzo[b,e]thiepin-11-ol with 2-bromoethanol in the presence of sulfuric acid in boiling benzene afforded the 2-bromoethyl ethers VIa and VIb which were transformed by substitution reactions with 1-methylpiperazine, 1-(2-hydroxyethyl)-piperazine and 1-(ethoxycarbonyl)piperazine to the title compounds. Alkaline hydrolysis of the carbamate IVa gave the secondary amine IIIa. Treatment of the bromo ether VIa with 4-(4-chloro-3-trifluoromethylphenyl)piperidin-4-ol resulted in the piperidine derivative VIIa. Substitution reaction of 11-chloro-6,11-dihydrodibenzo[b,e]thiepin with 1-(2-methoxyethyl)piperazine and 1-(2-ethoxyethyl)piperazine led to the amino ethers VIII and IX. Reaction of 11-chloro-11-phenyl-6,11-dihydrodibenzo[b,e]thiepin with 2-dimethylaminoethanethiol in dimethylformamide at 90°C gave a mixture of two isomeric bases which was separated to the expected sulfide X and the base XII, resulting evidently after the rearrangement of the primary carbocation. A similar reaction of 3-dimethylaminopropanethiol afforded a single product of structure XI. Out of the compounds prepared, the ether VIII was found most interesting: it is little toxic and has significant antireserpine activity in two tests (is considered a potential antidepressant). The ethers Iab, Iab, IIIa and VIIa did not reveal the expected neuroleptic activity.
2-氯和2-甲基-6,11-二氢二苯并[b,e]噻吩-11-醇与2-溴乙醇在硫酸存在下在沸腾的苯中反应,得到2-溴乙基醚VIa和VIb,然后通过与1-甲基哌嗪、1-(2-羟乙基)-哌嗪和1-(乙氧羰基)哌嗪的取代反应转化为标题化合物。对碳酸酯IVa的碱水解得到二级胺IIIa。用4-(4-氯-3-三氟甲基苯基)-哌啶-4-醇处理溴醚VIa得到哌啶衍生物VIIa。11-氯-6,11-二氢二苯并[b,e]噻吩与1-(2-甲氧基乙基)哌嗪和1-(2-乙氧基乙基)哌嗪的取代反应导致氨基醚VIII和IX。11-氯-11-苯基-6,11-二氢二苯并[b,e]噻吩与二甲基氨基乙硫醇在二甲基甲酰胺中在90°C反应,得到两种异构碱的混合物,分离出预期的硫醚X和碱XII,明显在初级碳阳离子重排后形成。3-二甲基氨基丙硫醇的类似反应产生了结构为XI的单一产物。在制备的化合物中,醚VIII被发现最有趣:它毒性较小,在两个测试中具有显著的抗去雄激素活性(被认为是潜在的抗抑郁药物)。醚Iab、Iab、IIIa和VIIa未显示出预期的神经阻滞活性。
