Abstract: A process is described for the preparation of a precursor alcohol of (±)-2-[thienyl(1-methyl-1H-pyrazol-5-yl)methoxy]-N,N-dimethyletanamine and in general for thienylazolylalcoxyethanamines and their enantiomers. The process involves asymmetric addition of a metalated thienyl reagent to a pyrazolcarbaldehyde in the presence of a chiral ligand to yield chiral alcohols. The chiral alcohols are further O-alkylated to yield the corresponding pharmaceutically active thienylazolylalcoxyethanamines.

Abstract: A process is described for the preparation of a precursor alcohol of Cizolirtine, (±)-2-[phenyl(1-methyl-1H-pyrazol-5-yl)methoxy]-N,N-dimethylethanamine and its enantiomers. The process involves the asymmetric reduction of a prochiral ketone in the presence of a chiral ruthenium (II) catalyst system including at least a bidentate phosphorous-containing ligand and a diamine ligand to yield chiral alcohols. The chiral alcohols are further O-alkylated to yield corresponding pharmaceutically active ethanamines.

Abstract: The invention relates to compounds having pharmacological activity towards the 5-HT7 receptor, and more particularly to some some tetrahydroisoquinoline substituted sulfonamide compounds, to processes of preparation of such compounds, to pharmaceutical compositions comprising them, and to their use for the treatment and or prophylaxis of a disease in which 5-HT is involved, such as CNS disorders.

Abstract: The present invention relates to Benzoxazinone-derived compounds of general formula (I), methods for their preparation, medicaments comprising these compounds as well as their use for the preparation of a medicament for the treatment of humans or animals.

Abstract: The procedure comprises reacting the mixture that comprises 2-[phenyl(1-methyl-1 H-pyrazole-5-yl)methoxy]-N,N-dimethylethanamine (I) with an enantiomer of an optically active acid to form a diastereoisomeric salt, separating said salt and liberating the enantiomer of said compound (I). The dextrorotatory enantiomer of (I) can be obtained by reacting a racemic mixture or non-racemic mixture of (I) with (+)-ditoluyl-L-tartaric acid, optionally mixed with p-toluensulphonic acid. Compound (I) has analgesic properties and its most active enantiomer is dextrorotatory.

Abstract: The procedure comprises (a) the enantioselective reduction of a pro-chiral ketone (III) by using a reducing and agent and chiral catalyst, both boron derivatives, in an anhydrous solvent or mixture of anhydrous solvents to form an enantiomer of an alcohol (II), and (b), the alkylation of (II), in phase transfer conditions, with optionally prior isolation and purification thereof, with 2-chloro-N,N-dimethylethylamine, to form an enantiomer of (I). Cyzolirtine exhibits analgesic properties.
