Compounds of formula (I) where R1 is of formulae (II), (III), or (IV), or (V); R2 is -R4, -O-R4, -O-S(O)2-R4, -NR4R5, R4-(CH2)b-NH(C-X)- (CH2)c-, R4-(CH2)b-O(C-O)NH-(CH2)c-(C=O)NH-R4-(C=O)NH-(C=O)NH-, -(CH2)b-NH(C= X) (CH2)c-R4, R4-(CH2)b-O(C=O)-(CH2)c-, -(CH2)b-O(C-O)-(CH2)c-R4, -NH(C=X)NH-R4, R4-O(C-O)O-, -O(C-O)NH-R4, R4-O(C-O)NH-, -(CH2)b-(C-O)-(CH2)c-R4, -NH-S(O)2-R4, -C(OH)R4R5, -CH(OH)-R4, -(C-O)-NR4R5, -CN, -NO2, substituted C1 to C6 alkyl, substituted or unsubstituted C1 to C6 alkenyl, or substituted or unsubstituted C1 to C6 alkynyl, said substituted moieties substituted with a moiety of the formulae -R4, -R4R5, -O-R4, or-S(O)d-R4; R3 is hydrogen, C1 to C6 alkyl, C1 to C6 alkylaryl, or aryl; R4 and R5 are each independently (XV), (XVI), (XVII), hydrogen, -CF3, C1 to C6 alkyl, C1 to C6 alkylaryl, with the proviso that when R2 is -R4 or -OR4, R4 is not hydrogen or C1 to C6 alkyl. These comrounds are useful psychotherapeutics and are potent serotonin (5-HT1) agonists and antagonists and may be used in the treatment of depression, anxiety, eating disorders, obesity, drug abuse, cluster headache, migraine, pain and chronic paroxysmal hemicranla and headache associated with vascular disorders, and other disorders arising from deficient serotonergic neyritransmission.
