| abstract |
The invention relates to a method for the enzymatic reduction of alkyne derivatives of the formula (1), n nwherein R 1 represents H, C 1 -C 6 -alkyl, C 2 -C 6 -alkenyl, or an optionally substituted carbocyclic or heterocyclic, aromatic or non-aromatic group, R 2 represents H, C 1 -C 6 -alkyl, C 2 -C 6 -alkenyl, by reaction in the presence of special reductases. |
