Formula I compounds with relative trans-configurations: (see formula I), where:.cndot X represents an oxygen atom or an NR2 group, .cndot. Y represents a group selected from -CH2-, -(CH2)2- AND -1CH=CH- , .cndot. R1 and R2 are the same or different, each representing a hydrogen atom or a group selected from alkyl, cycloalkyl, cycloalkylalkyl, in racemic form or optical isomer form, as well as their addition salts with pharmaceutically acceptable acids and their hydrates. The invention also relates to the method for preparing formula I compounds, their use, and the pharmaceutical compositions that contain them.
