Isoquinolines of the formula ##STR1## wherein R.sup.1 is H or alkyl of 1 - 4 carbon atoms, R.sup.2 is H and R.sup.3 is OH or R.sup.2 and R.sup.3 collectively are a C--C bond, and physiologically acceptable acid addition salts thereof have anti-depressant activity and can be prepared by solvolyzing or hydrogenolyzing a compound of the formula ##STR2## or an acid addition salt thereof, wherein R.sup.4 is R.sup.1 or R.sup.6, R.sup.5 is OR.sup.7 or, when R.sup.4 is R.sup.6, R.sup.3 ; R.sup.6 and R.sup.7 are radicals which can be split off solvolytically or hydrogenolytically and R.sup.1 and R.sup.2 are as above; and the optional step of dehydrating a resulting carbinol (R.sup.2 is H, R.sup.3 is OH) and/or treating a resulting compound (R.sup.1 is H) with a N-alkylating agent and/or converting a resulting base to a physiologically acceptable acid addition salt by treatment with and acid.
式为##STR1##其中R.sup.1为H或1-4个碳原子的烷基,R.sup.2为H,R.sup.3为OH或R.sup.2和R.sup.3共同为C-C键,其生理上可接受的酸盐具有抗抑郁活性,可通过溶解或氢解式为##STR2##的化合物或其酸加成盐来制备,其中R.sup.4为R.sup.1或R.sup.6,R.sup.5为OR.sup.7或当R.sup.4为R.sup.6时为R.sup.3; R.sup.6和R.sup.7是可通过溶解或氢解分离的基团,R.sup.1和R.sup.2如上所述; 可选步骤为脱水所得的羟基醇(R.sup.2为H,R.sup.3为OH)和/或用N-烷基化剂处理所得的化合物(R.sup.1为H)和/或通过与酸处理将所得的碱转化为生理上可接受的酸盐。
