| abstract |
The invention provides novel processes for making ethyl-4-cyano-3-hydroxybutyrate, e.g., (R)-ethyl 4-cyano-3-hydroxybutyric acid, and 4-cyano-3-hydroxybutyric acid. The invention provides protocols for making and 4-cyano-3-hydroxybutyric acid and ethyl-4-cyano-3-hydroxybutyrate by whole cell processes, cell lysate processes, “one pot processes” and “multi-pot” processes using a variety of parameters. |
