Compounds of the general formula I ##STR1## in which R.sub.1 and R.sub.2, which may be identical or different, each denote a hydrogen atom, a benzyl radical, a cyclohexylmethyl radical or a linear or branched alkyl radical containing from 1 to 10 carbon atoms, optionally substituted with a hydroxy radical, with a carboxy radical or with an alkoxy radical having 1 to 5 carbon atoms, with an alkoxycarbonyl radical having 2 to 6 carbon atoms, with an alkylphenyl radical having 7 to 16 carbon atoms or with a 2-alkylthienyl radical having 5 to 14 carbon atoms, R.sub.3 denotes a hydrogen atom or a linear or branched alkyl radical containing from 1 to 4 carbon atoms, A denotes a single bond or a methylene radical, or a radical of formula ##STR2## in which R.sub.4 is a linear or branched alkyl radical containing from 1 to 4 carbon atoms. These products are useful in anti-depressant, anti-aggressive, or dopaminergic modulation therapy and the corresponding bicyclic compounds are useful as intermediates for ring closure and production of the tricyclic compounds having the foregoing formula.
