Abstract
This invention related to the chemical formula 1 which represent by 1-(2'- to oxidize-2', 2' - two fluorin - D -furan ribose) - 4 - amido pyridine -2 - ketone or the method to produce its hydrochloride.
Description
Technical field
The present invention relates to the preparation method of 1-(2 '-deoxidation-2 ', 2 '-two fluoro-D-ribofuranosyls)-4-aminopyrimidine-2-ketone or its hydrochloride.
Background technology
1-(2 '-deoxidation-2 ', 2 '-two fluoro-D-ribofuranosyls)-4-aminopyrimidine-2-ketone (1-(2 '-deoxy-2 ', 2 '-difluoro-D-ribofuranosyl)-4-aminopyrimidin-2-on) [perhaps knownly has 2 '-deoxidation-2 ', 2 '-difluoro cytidine (Cytidine) or Ji Xita pyridine (Gemcitabine)] be 2 '-deoxidation-2 ' as known in the art, in 2 '-Difluoronucleosides series one.This compound has been disclosed among US 4526988 and the US 4808614, as antiviral agent and carcinostatic agent.
2 '-deoxidation-2 ', 2 '-Difluoronucleosides be by after preparing carbohydrate and alkali respectively, and these two compositions are carried out condensation prepared.Particularly, 2 '-deoxidation-2 ', the beta-nucleosides compound is very effective in 2 '-Difluoronucleosides, and the typical compound of such beta-nucleosides is known the Ji Xita pyridine.
US 4526988 discloses the 2 '-deoxidation-2 ' that will be dissolved in the protection hydroxyl in the methylene dichloride; 2 '-two fluoro-D-ribofuranosyls; in suitable de-acidying agent such as triethylamine; reacted 3 hours at 25 ℃ with Methanesulfonyl chloride; 1-methyl sulphonyl-the 2 '-deoxidation-2 ' of preparation protection hydroxyl, 2 '-two fluoro-D-ribofuranose radical derivatives.The gained compound combines with purine (purine) or pyrimidine (pyrimidine) alkali, forms the one-tenth glycosides isomer (anomer) (anomer) of nucleosides.
In addition, Korean Patent Registration discloses have erythro (erythro) and the stereochemical 2 '-deoxidation-2 ' of β, the preparation method of 2 '-Difluoronucleosides for No. 117181.
Though nucleosides synthesizes creative development, still needs to develop β-2 '-deoxidation-2 ', the preparation method of the industrial production of 2 '-Difluoronucleosides.
Summary of the invention
