<p>The invention relates to compounds of formula (I), wherein X stands for hydroxyl group, halogen or R-SO3-group, wherein R means an optionally substituted alkyl or aryl group; each of A and B represents hydrogen or A and B together can form a valence bond, as well as cis and trans isomers, optically active enantiomers and racemates thereof and the salts of these compounds. The novel compounds of formula (I) of the invention are valuable intermediates for the preparation of paroxetine, an antidepressant drug. Furthermore, the invention relates to a process for the preparation of novel compounds of formula (I), wherein X, R, A and B are as defined above, as well as cis and trans isomers, optically active enantiomers and racemates thereof and the salts of these compounds; as well as to the use of these substances for the preparation of paroxetine of formula (V).</p> |
