ASYMMETRICAL HYDROGENATION OF DIHYDROFLOIMIDAZOLE DERIVATIVE |
| 摘要 |
<p>A novel process is described for the asymmetric hydrogenation of furoimidazole derivatives of the general formula <IMAGE> using hydrogen in the presence of a homogeneous catalyst to give the corresponding diastereomeric tetrahydrofuroimidazole derivatives of the general formula <IMAGE> which are intermediates for the preparation of the vitamin (+)-biotin.</p> |
