Reactions of 4,4'-dihalogenated benzhydrols and 1,1-diphenylethanols Xab and XIab with sodium hydride and 2-dimethylaminoethyl chloride and 2-pyrrolidinoethyl chloride afforded the ethers Vab-VIIIab. 2-Bromoethyl ethers IXab, obtained from the benzhydrols Xab and 2-bromoethanol by treatment with sulfuric acid, were subjected to substitution reactions with 4-phenylpiperidin-4-ol, 4-(2-tolyl)piperidin-4-ol (XVI), 4-(4-fluorophenyl)piperidin-4-ol and 4-(2-oxobenzimidazolin-1-yl)piperidine (XVII) and gave the amino ethers XIIab-XIVab and XIXab. The products were evaluated as potential antiparkinsonic agents and compared with flunamine (III). The ethers Va, Vb and VIa disclosed anticataleptic activity of a similar degree like that of flunamine (III).
4,4'-二卤代苯基甲醇和1,1-二苯基乙醇Xab和XIab与氢氧化钠和2-二甲氨基乙基氯化物以及2-吡咯烷基乙基氯化物的反应产生了醚类化合物Vab-VIIIab。从苯基甲醇Xab和2-溴乙醇在硫酸的处理下得到2-溴乙基醚类化合物IXab,随后将其进行取代反应,反应物为4-苯基哌啶-4-醇、4-(2-甲苯基)哌啶-4-醇(XVI)、4-(4-氟苯基)哌啶-4-醇和4-(2-氧代苯并咪唑啉-1-基)哌啶(XVII),产生了氨基醚类化合物XIIab-XIVab和XIXab。这些产物被评估为潜在的抗帕金森病药物,并与flunamine(III)进行比较。醚类化合物Va、Vb和VIa显示了与flunamine(III)相似的抗痉挛活性。
