The present invention relates to compounds exhibiting central nervous system (CNS) activity which are useful in the treatment of epilepsy and other CNS disorders. The compounds of this invention have the following general formula:
and pharmaceutically acceptable salts thereof wherein
R is aryl, aryl lower alkyl, heterocyclic or heterocyclic lower alkyl, wherein R is unsubstituted or is substituted with at least one electron withdrawing group or an electron donating group;
R₁ is hydrogen or lower alkyl and R₁ is unsubstituted or is substituted with at least one electron withdrawing substituent or at least one electron donating substituent;
R₂ and R₃ are independently each hydrogen, lower alkenyl, lower alkynyl, aryl lower alkyl, aryl, heterocycli, heterocycli lower alkyl or Z-Y, wherein R₂ and R₃ may be unsubstituted or substituted with at least one electron withdrawing group or electron donating group;
Z is O, S, NR₄, PR₄ or a chemical bond;
Y is hydrogen, lower alkyl, aryl, aryl lower alkyl, lower alkenyl, lower alkynyl, or halo, and Y may be unsubstituted or substituted with at least one electron donating group or electron donating group; provided that when Y is halo, Z is a chemical bond or
ZY taken together is NR₄NR₅R₆, NR₄OR₅, ONR₄R₅, OPR₄R₅, PR₄OR₅, SNR₄R₅, NR₄SR₅, SPR₄R₅, PR₄SR₅, NR₄PR₅R₆ or PR₄NR₅R₆,
R₄, R₅ and R₆ are independently hydrogen, lower alkyl, aryl, aryl lower alkyl, lower alkenyl, lower alkynyl, and R₄, R₅ and R₆ may be unsubstituted or substituted with an electron withdrawing group or an electron donating group and
n is 1-4.
