Zusammenfassung:	Compounds of the following general formula I wherein: X and Y are different from each other and represent -CH2- or an oxygen atom; R represents a radical selected from hydroxy, bromo, acetoxy, pyrrolidino, morpholino, piperazino and piperazino substituted at the position 4 by a carbethoxy, benzyl, phenyl, halophenyl, methoxyphenyl or trifluoromethylphenyl group, or when X is -CH2- and Y is an oxygen atom, R may represent also chloro; methods for their preparation; pharmaceutical compositions containing them. The compounds possess a remarkable antitussive activity.
