Fused isoquinoline derivatives of the general formula ##STR1## wherein: A is a divalent radical selected from the groups ##STR2## wherein R.sub.3 and R.sub.4 each independently represents hydrogen, alkyl,, alkenyl, cycloalkyl, aryl, aralkyl, aralkenyl, cycloalkyl-alkyl or, taken together with the adjacent double bond, represent a cycloalkene containing from 5 to 8 carbon atoms or an aromatic nucleus; R.sub.5 represents hydrogen, hydroxyl, alkyl, alkenyl, cycloalkyl, aryl, aralkyl, aralkenyl or cycloalkyl-alkyl; Y is .dbd.O, .dbd.S or .dbd.NH; X is --O--, --S-- or --NR.sub.6 -- wherein R.sub.6 represents hydrogen, alkyl, cycloalkyl, aryl, aralkyl or cycloalkyl-alkyl; R.sub.1 and R.sub.2 each independently represents hydrogen, alkyl, phenyl, cycloalkyl, alkoxy, alkenyloxy, methylenedioxy, cycloalkoxy, halo or di-alkylamino or, taken together with the adjacent carbon atoms of the benzene ring, form a cycloalkenyl group containing 5 or 6 carbon atoms or an aromatic nucleus fused on the benzene ring. The compounds are essentially prepared through thermal cyclization of a compound of the formula ##STR3## wherein A, X, Y, R.sub.1 and R.sub.2 have the same meanings given before, with the proviso that R.sub.1 and R.sub.2 cannot simultaneously occupy both the ortho positions, B represents hydrogen, R represents an --OR.sub.7 or --NR.sub.8 R.sub.9 radical wherein R.sub.7 is alkyl, aryl or aralkyl and R.sub.8 and R.sub.9 each independently represents hydrogen, alkyl, aryl, aralkyl, or taken together with the adjacent nitrogen atom represent a heterocyclic saturated radical of 5 or 6 atoms which may contain a further hetero-atom selected from oxygen and nitrogen, or the symbols B and R taken together represent a further bond between the adjacent carbon and nitrogen atoms.
通用公式为##STR1##的融合异喹啉衍生物,其中:A是从组##STR2##中选择的二价基团,其中R.sub.3和R.sub.4分别独立表示氢、烷基、烯基、环烷基、芳基、芳基烷基、芳基烯基、环烷基-烷基,或者与相邻的双键一起表示含有5至8个碳原子的环烷烯或芳香核;R.sub.5表示氢、羟基、烷基、烯基、环烷基、芳基、芳基烷基、芳基烯基或环烷基-烷基;Y是.dbd.O、.dbd.S或.dbd.NH;X是--O--、--S--或--NR.sub.6--,其中R.sub.6表示氢、烷基、环烷基、芳基、芳基烷基或环烷基-烷基;R.sub.1和R.sub.2分别独立表示氢、烷基、苯基、环烷基、烷氧基、烯基氧基、亚甲二氧基、环烷氧基、卤素或二烷基氨基,或者与苯环的相邻碳原子一起形成含有5或6个碳原子的环烷烯基团或融合在苯环上的芳香核。这些化合物基本上是通过化合物的热环化制备的##STR3##其中A、X、Y、R.sub.1和R.sub.2的含义与前述相同,但R.sub.1和R.sub.2不能同时占据邻位,B表示氢,R表示--OR.sub.7或--NR.sub.8 R.sub.9基团,其中R.sub.7是烷基、芳基或芳基烷基,R.sub.8和R.sub.9各自独立表示氢、烷基、芳基、芳基烷基,或者与相邻的氮原子一起表示含有5或6个原子的杂环饱和基团,其可能包含进一步选择的氧和氮杂原子,或者符号B和R一起代表相邻碳原子和氮原子之间的进一步键。
