A compound having the formula or a pharmaceutically acceptable salt thereof wherein R is hydrogen or hydroxy; R1 is hydrogen, alkyl, arylalkyl, (CH2)nOH, or (CH2) NR7R8; R5 and R6 are each independently hydrogen, halogen, NO2, CN, CF3, SO2NR7R8, PO3R9R10, alkyl, alkenyl, alkynyl, (CH2)nCONR7R8, (CH2)nCO2R10, NHCOR11, wherein R7 and R8 are each independently hydrogen or alkyl or together R7 and R8 form a ring of from three to seven atoms, R9 is hydrogen or alkyl, R10 is hydrogen or alkyl, R11 is hydrogen or alkyl, and n is an integer of from zero to four; A is a ring of five to seven atoms fused with the benzo ring at the positions marked a and b, and formed by the following bivalent radicals: a-NR12—CHR13—CHR14-b, a-CHR13—CHR14—NR12-b, a-CHR13—NR12—CHR14-b, a-CHR14—CH2—NR12—CHR13-b, a-CHR13—NR12—CH2—CHR14-b, a-CH2—CH2—CHR13—NR12-b, a-NR12—CHR12—CHR13—CH2—CH2-b, a-CH2—CH2—NR12—CH2—CH2-b, a-CH2—CH2—CH2NR12—CH2-b, a-CH2—NR12—CH2—CH2-b a-CH2—CH2—CH2—CH2—NR12-b, a-NR12—CH2—CH2—CH2—CH2-b, wherein R12 is hydrogen, CH2CH2OH, or alkyl, and R13 and R14 are each independently hydrogen, CN, CONH2, CH2NH2, CH2OH, alkyl, arylalkyl, alkenyl, or CO2R15, wherein R15 is hydrogen or alkyl. The compounds are useful in the treatment of disorders of mammals, responsive to the blockade of glutamic and aspartic acid receptors. Processes for preparing the compounds and novel intermediate useful in the processes are also included.
