Novel enantiomeric and diastereoisomeric forms of decahydroquinolines of the formula ##STR1## wherein R.sub.1 and R.sub.2 are individually selected from the group consisting of hydrogen and alkyl of 1 to 5 carbon atoms or taken together with the nitrogen atom to which they are connected form a 5 to 6 member heterocycle optionally including another heteroatom and optionally substituted, A is selected from the group consisting of --(CH.sub.2).sub.n -- and alkylene substituted with an alkyl and having 2 to 8 carbon atoms, n is an integer from 0 to 5, Z is selected from the group consisting of optionally substituted phenyl, naphthyl indenyl, monocyclic heterocycle of 5 to 6 members and a bicyclic heterocycle all being unsubstituted or substituted by one or more substituents and their non-toxic, pharmaceuically acceptable acid addition salts and quaternary ammonium salts having central analgesic properties.
                            化合物的新对映异构体和顺反异构体,其
化学式为##STR1##其中R.sub.1和R.sub.2分别选自氢和1到5个碳原子的烷基的群体,或与它们连接的氮原子共同形成一个5到6个成员的杂环,该杂环可包括另一个杂原子,并可选择性地被取代,A选自--(CH.sub.2).sub.n --和被烷基取代且具有2到8个碳原子的烷基,n为0到5的整数,Z选自可选择性取代的苯基、
萘基、
茚基、5到6个成员的单环杂环和双环杂环,所有这些均未被取代或被一个或多个取代基取代,以及它们的无毒、药学上可接受的酸盐和季
铵盐,具有中枢镇痛作用。
