Process for the preparation of aromatic carbamoyl-substituted

Process for the preparation of an optically pure enantiomer of formoterol

Substituted oxazolidines

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.

5-(3-formylamino-4-hydroxyphenyl)-3-(1-

Finely particulate cellulose esters of aromatic or aromatic-aliphatic carboxylic acids in the form of substantially spherical, partially crystalline particles having an average diameter of 1 to 200 .mu.m and a specific surface area of 10 to 300 m.sup.2 /g, are suitable for use as stationary phase in methods of chromatographic separation, especially for the resolution of racemates.

Finely particulate cellulose esters of aromatic or aromatic-aliphatic

Process for the preparation of finely divided porous cellulose in the form of essentially spherical particles by formation of a suspension, in which an organic solution of a cellulose ester of aromatic or aromatic-aliphatic carboxylic acids containing a C.sub.5 -C.sub.12 alkanol is stirred into an aqueous solution of an anionic surfactant, the solvent is removed and the particles are isolated and hydrolyzed under heterogeneous conditions. They are suitable as adsorbents in e.g. chromatographic processes.

Process for the preparation of finely divided porous cellulose particles

The invention relates to enantiomers of 1-(6-phenoxy-2-pyridyl)ethanols of the formula ##STR1## wherein * is (+) or (-) and X and Y are each independently of the other hydrogen, halogen, nitro, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.5 alkenyl or C.sub.2 -C.sub.5 alkynyl. The invention also relates to the preparation of these enantiomers and to their use for the preparation of biocidal compounds.
