New aminoethyl ketals, the new processes for obtaining these compounds and the pharmaceutical compositions containing them

摘要

The present invention relates to the field of organic chemisty and more particularly to the field of therapeutic chemistry. It relates specifically to aminoethyl ketals of general formula I <IMAGE> in which R1 and R2 represent a lower alkyl radical, an aryl radical, a heteroaryl radical, a cycloalkyl radical or a (cycloalkyl)aryl radical, R4 and R5 represent hydrogen, an alkyl radical, an alkenyl radical, a cycloalkyl radical, a dicycloalkylalkyl radical, a cycloalkenyl radical, an aryl radical, an arylalkyl radical, a heteroarylalkyl radical, an alkoxycarbonyl radical, an aminocarbonyl radical or an acyl radical or else R4 and R5 form, with the nitrogen atom to which they are attached, a mono- or bicyclic cyclic structure, in the free or salified form. These compounds are used as active principles in medicaments.
