AbstractThe synthesis of enantio‐ and diastereomerically pure γ‐butyrolactones is described using a one‐pot, two‐enzyme cascade. Ethyl 2‐methyl‐4‐oxopent‐2‐enoate (2) was reduced selectively first in a 1,4‐reduction using the old yellow enzyme (OYE1) [EC 1.6.99.1] and consecutively in a 1,2‐reduction by an alcohol dehydrogenase [EC 1.1.1.2].
