Method of producing oxybutynin and its derivatives |
| 摘要 |
An oxybutynin and its derivatives are produced by reacting a phenylketone with a silylcyanide in the presence of a specified asymmetric catalyst to obtain a siloxynitrile, and then reacting the siloxynitrile with a reducing agent and oxidizing the resulting aldehyde, or subjecting the siloxynitrile to a hydrolysis.
