    Abstract: The present invention relates to a process for the preparation of enantiomerically pure (S)-3-methyl-amino-1-(thien-2-yl)propan-1-ol of the formula II-S by obtainment of (S)-3-hydroxy-3-thien-2-ylpropionitrile from its enantiomer mixture with the R isomer and the subsequent reaction of (S)-3-hydroxy-3-thien-2-ylpropionitrile with hydrogen and methylamine in the presence of a catalyst to give II-S.

    Abstract: The present invention relates to novel enzyme-containing polymers, having at least one of the following structural elements (1 and 2), wherein the abbreviations and symbols have the following meaning: E stands for enzyme; X 1, X2 independently represent oxygen, sulfur or NH from a functional group of t he enzyme; Q represents hydrogen or group (a); A1, A2, A3, A4 independently represent oxygen or sulfur; p is 0 or 1 with the proviso that A1, A2, A3 and A4 represent oxygen when p = 0; w is 1-4; q is 1-4; v is 1-100; R1 represent s an optionally substituted or functionalized hydrocarbon group with two to fi ve bonds; R2 represents an optionally substituted or functionalized hydrocarbon group with two to five bonds; R4 and R5 independently represent hydrogen, a C1- C4-alkyl, aryl or alkylaryl group. The invention further relates to a method for the production of said enzyme-containing polymers, their utilization as catalysts in chemical reactions and their use for separating enantiomer mixtures.
