Dimethyl quaternary salts of cis- and trans-piperidine-3, 4-diol acetonides (9 and 15) were prepared from readily available intermediates, 1-benzoyl and 1-ethoxycarbonyl derivatives of 1, 2, 5, 6-tetrahydropyridine (4a and 4b). The activity of 9 was examined and the presence of the rigid skeleton was shown to markedly decrease the cholinomimetic effect compared with the partially opened skeleton. The relationship between 9 and known potent muscarinic agents is discussed.
顺式和反式-哌啶-3, 4-二醇乙酰酮的二甲基季铵盐(9和15)是由易于获得的中间体1-苯甲酰基和1-乙氧基碳酰基的1, 2, 5, 6-四氢吡啶衍生物(4a和4b)制备而成。对9的活性进行了研究,并表明刚性骨架的存在显著降低了与部分打开骨架相比的胆碱仿效效应。讨论了9与已知的强效毒蕈碱剂之间的关系。
