Abstract: The invention relates to substantially photochemically or thermally cross-linked polysaccharide derivatives in which the OH groups as OR groups have been esterified or converted into carbamate (urethane) or mixtures thereof and that do not contain photopolymerisable functional groups prior to the cross-linking. They can be used as carrier materials for the chromatographic separation of enantiomers.

Abstract: The present invention relates to photochemically cross-linked derivatives of general formulae (IA) and (IB), wherein R is a polysaccharide radical in which the OH groups have been esterified as OR' groups or converted into a carbamate (urethane), R.sub.1, and R.sub.2 are each independently lower alkyl or unsubstituted or substituted aryl, X is a direct bond or phenylene, m is 0 or 1, and n is 0 or an integer from 1 to 20, to processes from the preparation thereof and to the use thereof. The compounds of general formula (IA) and (IB) can be used as supports in the chromatographic separation of enantiomers.

Abstract: The invention relates to a process for the preparation of polysaccharide-N-arylcarbamates in suitable form as supports for chromatography, which process comprises adding to polysaccharide carbamates, which may be substituted in the aryl moiety, an N-aryl-1-lower-alkylcarbamate-containing solution of an organic solvent, with vigorous stirring, until the polysaccharide derivative is completely dissolved and then adding thereto an aqueous solution containing a high molecular weight surfactant and, with continued stirring, removing the organic solvent from the emulsion so obtained and isolating the solid particles and washing and drying them. The polysaccharide derivatives so obtained can be used as support materials for the chromatographic separation of enantiomers.

Abstract: The present invention is directed to a process for preparing formoterol and related compounds and derivatives thereof and their pharmacologically and pharmaceutically acceptable fumarate salts and/or solvates. The present invention is also directed to certain formoterol related compounds per se.

Abstract: The invention relates to novel substituted oxazolidines of formula (I) wherein R.sub.1 and R.sub.2 are simultaneously hydrogen or both together are the identical lower alkyl radical, and to the salts thereof in racemic and chiral form, to a process for the preparation of said compounds, to pharmaceutical compositions containing them, and to the use thereof as medicaments. The compounds have a stimulating effect on beta-adrenergic receptors and can be used, inter alia, for the treatment of diseases associated with reversible obstruction of the respiratory tract, typically asthma and chronic bronchitis, and also for inflammation of different origin.

Abstract: The present invention relates to novel oxazolidines of formula (1) ##STR1## wherein R.sub.1 and R.sub.2 are simultaneously hydrogen or both are the same lower alkyl radical or together are 4- to 7-membered lower alkylene, and to the salts thereof in racemic and chiral form, to the preparation of these novel compounds, to pharmaceutical compositions containing them and to the use thereof as medicaments. The compounds have a stimulating effect on beta-adrenergic receptors and can be used, inter alia, for the treatment of diseases associated with reversible obstruction of the respiratory tract, typically asthma and chronic bronchitis, and also for inflammations of different origin.
