| abstract |
The object of the invention is heterocyclic compounds of general formula (I) endowed with anticonvulsant activity: ##STR1## in which Y is selected from --O--, --S-- and ##STR2## R 4 being H or optionally substituted alkyl, acyl or benzyl, Z is selected from the groups --CO--N(R 6 )--,--NH--CO--CH═CH-- and --N(R 6 )--CO, R 6 being H or alkyl; n R 1 is C 1 -C 4 alkyl; R 2 is C 1 -C 4 alkyl or halogen; R 3 represents optionally substituted C 1 -C 4 alkyl, alkoxy or hydroxyalkyl, or C 2 -C 7 alkanoyl. |
