Abstract
Alkyl esters, dialkylamides and heterocyclic amides of 4-amino-alkyl-4-cyano-4-phenyl-butanoic and but-2-enoic acids substituted in at least one of the 2 and 3 positions by a C.sub.1 -C.sub.4 alkyl group or by a divalent alkylene radical which together with at least one of the carbon atoms at said 2 and 3 positions forms a carbocyclic ring of 3 to 8 carbon atoms are novel intermediates involved in the preparation of pharmacologically active compounds. They also have pharmacological, in particular central nervous system, especially anti-depressant or cardiovascular activity. Several methods are disclosed for preparing the novel compounds.
