  • Antivertigo agents. IV. Synthesis and antivertigo activity of 6-(.OMEGA.-(4-aryl-1-piperazinyl)alkyl)-5,6,7,8-tetrahydro-1,6-naphthyridines.

    A series of novel 6-[ω-(4-aryl-1-piperazinyl) alkyl]-5, 6, 7, 8-tetrahydro-1, 6-naphthyridines was synthesized and evaluated for antivertigo activity by testing their ability to inhibit spontaneous nystagmus in cats. Structure-activity relationships are discussed. Many of the compounds having the 4-(2-alkoxyphenyl) piperazine group as the 4-arylpiperazine moiety showed more potent antivertigo activity than diphenidol. Among them, 2-2-[4-(2-ethoxyphenyl)-1-piperazinyl] ethyl}-1, 2, 3, 4, 6, 7, 8, 9-octahydrobenzo [b] [1, 6] naphthyridine (NK 422, 41) was selected as a promising antivertigo agent. NK 422 also exhibited a more potent inhibitory effect on apomorphine-induced vomiting in dogs than diphenidol.

    reduction of the imine prepared by intramolecular reaction of the acyl and amine groups. The amine group was introduced via deprotonation of the methyl group in bromopicoline, its reaction with dimethylcarbonate, reduction to the corresponding alcohol and Mitsunobu reaction with phthalamide. The acyl group was placed at the bromine position via the Stille cross-coupling reaction of tributyl(1-ethoxyvinyl)stannane
    从容易获得的3-溴-甲基吡啶开始制备了三种新的四氢萘啶。所提出策略的关键步骤包括还原通过酰基和胺基的分子内反应制备的亚胺。胺基通过溴甲基吡啶中的甲基去质子化,与碳酸二甲酯的反应,还原成相应的醇和与邻苯二甲酰胺的光延反应而引入。通过三丁基(1-乙氧基乙烯基)锡烷的Stille交叉偶联反应,然后水解,将酰基置于溴的位置。所提出的化学序列使得可以对四氢-2,7-和1,6-萘啶进行多毫克制备。
