1-(11H-Dibenz[b,f]-1,4-oxathiepin-11-yl)methyl-4-piperidone (XIII), which was obtained from 11H-dibenz[b,f]-1,4-oxathiepin-11-carboxylic acid (VIII) in four steps, was treated with isobutylmagnesium bromide and gave the title compound V in addition to the prevailing quantity of the secondary alcohol VI, i.e. the product of reduction. Synthesis of a series of trisubstituted benzyl phenyl sulfide derivatives XVIII-XXIV, XXVI-XXXI is described; these compounds are potential intermediates in the preparation of 11H-dibenz[b,f]-1,4-oxathiepinacetic acids XVI and XVII. Chloromethylation of 11H-dibenz[b,f]-1,4-oxathiepin (VII) and two further usual steps gave an acid to which structure XVI is assigned. Compound V is an open model of "oxathiaisobutaclamol" and in agreement with this fact it behaves like a neuroleptic agent: it increases the turnover and metabolism of dopamine in the rat brain striatum which is manifested by a significant rise of homovanillic acid level.
1-(11-二苯并[b,f]-1,4-噁硫杂环庚-11-基)甲基-4-哌啶酮(XIII),经过四步从11-二苯并[b,f]-1,4-噁硫杂环庚-11-羧酸(VIII)得到,经异丁基溴化镁处理后得到标题化合物V,同时还有大量的二级醇VI,即还原产物。描述了一系列三取代苄基苯基硫醚衍生物XVIII-XXIV,XXVI-XXXI的合成;这些化合物是制备11-二苯并[b,f]-1,4-噁硫杂环庚乙酸XVI和XVII的潜在中间体。对11-二苯并[b,f]-1,4-噁硫杂环庚(VII)进行氯甲基化和另外两个常规步骤得到一种酸,其结构被指定为XVI。化合物V是“噁硫异丁氯胺醇”的开放模型,与这一事实一致,它表现为一种神经阻滞剂:它增加了大鼠脑纹状体中多巴胺的周转和代谢,表现为3,4-二羟基苯乙酸水平显著升高。
