    摘要: Method for producing N-heterocyclic optically active alcohols of the formula (I), where R
    1 represents alkyl groups which in turn can be monosubstituted or polysubstituted by alkyl, halogen, SH.SR
    3 , OH, OR
    3 , NO
    2 , CN, CO, COOR
    3 , NR
    3 R
    4 or NR
    3 R
    3 R
    5+ X
    - , where R
    3 , R
    4 and R
    5 independently of one another are H or a low-alkyl or low-alkoxy radical and X
    - is a counterion, R
    2 is N-containing heteroaryl groups which in turn can be monosubstituted or polysubstituted by alkyl, halogen, SH.SR
    3 , OH, OR
    3 , NO
    2 , CN, CO, COOR
    3 , NR
    3 R
    4 or NR
    3 R
    3 R
    5+ X
    - , where R
    3 , R
    4 and R
    5 independently of one another are H or a low-alkyl or low-alkoxy radical and X
    - is a counterion, by reduction of the corresponding ketone, wherein the reduction is carried out using a dehydrogenase having the polypeptide sequence SEQ ID NO: 2 or NO: 4, or having a polypeptide sequence in which up to 25% of the amino acid radicals are modified in comparison with SEQ ID NO: 2 or NO: 4 by deletion, insertion, substitution or a combination thereof.
