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.sub.4 being H or optionally substituted alkyl, acyl or benzyl, Z is selected from the groups --CO--N(R.sub.6)--,--NH--CO--CH.dbd.CH-- and --N(R.sub.6)--CO, R.sub.6 being H or alkyl; R.sub.1 is C.sub.1 -C.sub.4 alkyl; R.sub.2 is C.sub.1 -C.sub.4 alkyl or halogen; R.sub.3 represents optionally substituted C.sub.1 -C.sub.4 alkyl, alkoxy or hydroxyalkyl, or C.sub.2 -C.sub.7 alkanoyl.
