Heterocyclic compounds, pharmaceutical compositions comprising them and process for the preparation thereof

摘要

The invention relates to anxiolytic pharmaceutical compositions comprising as active ingredient 1-sytrylisoquinoline derivatives of general formula (I), wherein n is 1, 2, 3 or 4; R may be the same or different and represent(s) hydrogen, lower alkyl, lower alkoxy or hydroxy, or two substituents R attached to adjacent carbon atoms may form together an alkylenedioxy group; R1 represents hydrogen or lower alkyl, and Ar stands for an optionally substituted aryl or heteroaryl, Some of the compounds of general formula (I) is known, but the majority thereof has not so far described in the literature. The invention also encompasses the preparation of the new compounds of general formula (I), which comprises reacting a compound of general formula (II) with an aldehyde or general formula (III) in the presence of a condensing agent or an acidic catalyst.
