ASYMMETRIC HYDROGENATION OF FUROIMIDAZOLE DERIVATIVES

摘要

2134441 9424137 PCTABS00034 A process for the asymmetric hydrogenation of furoimidazole derivatives of general formula (I) with hydrogen in the presence of a homogeneous catalyst to give the corresponding diastereomeric dihydrofuroimidazole derivatives of general formula (II). The dihydrofuroimidazole derivatives of general formula (II) are intermediates for the preparation of (+)-biotin.
