Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl 3-Hydroxybutyrate | HCID 62572 | — |
| Reactant | Ethyl 4-cyano-3-hydroxybutanoate | HCID 4184461 | — |
| Product | Ethyl (3R)-4-cyano-3-hydroxybutanoate | HCID 2733879 | 99% |
Reaction Steps
Instead of ethyl 3-hydroxybutyrate used in Example 1, ethyl 4-cyano-3-hydroxybutyrate (1%, w/v) was used as a reactant and novozyme 435 lipase was used as a biocatalyst. After reaction for 3 hours, ethyl (R)-4-cyano-3-hydroxybutyrate (99% e.e) was obtained at 57.3% conversion.
