摘要
The glycosidase inhibitor 1-deoxymannonojirimycin (1,5-dideoxy-1,5-imino-D-mannitol) was synthesized in four simple steps from sucrose via 6,6'-diazido-6,6'-dideoxysucrose and 6-azido-6-deoxy-D-fructofuranose. The ''isomeric ballast'' of the sequence, 6-azido-6-deoxy-D-glucose, could be partially converted into 6-azido-6-deoxy-D-fructofuranose with the aid of glucose isomerase (E.C. 5.3.1.5) demonstrating a novel synthetic application of this enzyme. The sequence allows access to multigramm quantities of 1-deoxymannonojirimycin in over 30 % overall yield without the need for expensive reagents and protecting group manipulations.
