6-Fluorophthalide (IV), obtained from 6-aminophthalide by the Schiemann method, was transformed by reactions with potassium salts of thiophenol and 4-fluorothiophenol and 4-fluorothiophenol to the acid V and VI. Cyclization with polyphosphoric acid gave 9-fluoro- and 2,9-difluorodibenzo[b,e] thiepin-11(6H)-one (VII, VIII) which were treated with 3-dimethylaminopropylmagnesium chloride and afforded the tertiary alcohols IX and X. Dehydration by heating with dilute hydrochloric acid resulted in the title compounds II and III whose IR spectra indicated the E-configuration. Both compounds showed properties of tricyclic antidepressants being, however, less active than prothiadene (I) in the tests for the antireserpine activity.
6-氟邻苯二酮(IV),通过Schiemann方法从6-氨基邻苯二酮获得,经过与硫酚钾盐和4-氟硫酚钾盐反应转化为酸(V)和(VI)。与聚磷酸环化后得到9-氟和2,9-二氟二苯并噻吩-11(6H)-酮(VII, VIII),经3-二甲氨基丙基镁氯化物处理得到三级醇(IX)和(X)。通过与稀盐酸加热脱水得到标题化合物(II)和(III),其红外光谱表明呈现E构型。这两种化合物表现出三环抗抑郁药物的特性,但在抗利血平活性测试中比普罗替丹(I)活性稍弱。
