| titleOfInvention | PROCESS FOR PRODUCING ALPHA-ANOMER ENRICHED 2-DEOXY-2,2-DIFLUORO-D-RIBOFURANOSYL SULFONATE AND USE THEREOF FOR THE PRODUCTION OF BETA NUCLEOSIDE |
| abstract | A process of preparing an alpha-anomer enriched 2- deoxy-2 , 2-dif luoro-D-ribofunanosyl sulfonate, which is useful as an intermediate in the preparation of a beta nucleoside, such as gemcitabine, an anti-tumor agent. A beta-2-deoxy-2, 2-difluoro-D-ribofunanosyl sulfonate is heated and converted to an alpha-2-deoxy-2, 2-difluoro-D- ribofunanosyl sulfonate in the absence of an effective amount of a sulfonate salt to facilitate the conversion. In addition, an anomeric mixture of an alpha-anomer and a beta-anomer of 2-deoxy-2, 2-difluoro-D-ribofunanosyl sulfonate can be dissolved in a mixture of water and a solvent and heated to produce a lactol, which may be further converted to jan alpha-anomer enriched 2-deoxy- 2 , 2-difluoro-D-ribofunanosyl sulfonate . |
