A new process for preparing s-triazolo[5,1-a]-isoquinoline derivatives of the formula ##STR1## wherein A represents the group --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH--; R is selected from hydrogen, amino, lower alkylamino, di-lower alkylamino, acylamino, diacylamino, ureido, thioureido, carbethoxythioureido, benzoylthioureido, sulfhydryl, lower alkyl, trifluoromethyl, phenyl, substituted phenyl, pyridyl, methylpyridyl and dimethylpyridyl; and R.sub.1 and R.sub.2 each independently represents hydrogen or lower alkoxy; by condensation of a 2-amino-3,4-dihydro-1(2H)-isoquinolinone with an imidolyl, cyanamide, cyanic or thiocyanic derivative. New compounds of the formula I wherein A represents the group --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH--, R has the same meaning as above with the exclusion of hydrogen, methyl, phenyl, and trifluoromethyl, R.sub.1 and R.sub.2 have the same meaning as above, with the proviso that when A represents the group --CH.dbd.CH--, R cannot be tolyl or pyridyl. The new compounds and some of the intermediates of the process are active as antiinflammatories, CNS depressants and anti-fertility agents.
一种制备式##STR1##所示的s-三唑并[5,1-a]-异喹啉衍生物的新方法,其中A代表基团--CH2--CH2--或--CH═CH--;R选自氢、氨基、低级烷基氨基、二低级烷基氨基、酰氨基、二酰氨基、脲基、硫脲基、乙氧羰基硫脲基、苯甲酰硫脲基、巯基、低级烷基、三氟甲基、苯基、取代苯基、吡啶基、甲基吡啶基和二甲基吡啶基;且R1和R2各自独立地代表氢或低级烷氧基;该方法通过2-氨基-3,4-二氢-1(2H)-异喹啉酮与咪唑基、氰胺、氰酸或硫氰酸衍生物的缩合反应实现。式I的新化合物中,A代表基团--CH2--CH2--或--CH═CH--,R具有上述相同的含义,但不包括氢、甲基、苯基和三氟甲基,R1和R2具有上述相同的含义,但前提是当A代表基团--CH═CH--时,R不能是甲苯基或吡啶基。这些新化合物及其过程中的一些中间体具有抗炎、中枢神经系统抑制和抗生育活性。
