Paragraph 0060-0067; 0086, (2018/04/01)
The invention relates to 1-(2-deoxidized-beta-D-ribofuranose)-5-iodo-2-pyrimidone, and particularly relates to a preparation method of 1-(2-deoxidized-beta-D-ribofuranose)-5-iodo-2-pyrimidone. The preparation method comprises the following steps of performing a reaction on 2-hydroxypyrimidine hydrochloride and a glacial acetic acid/iodine monochloride solution so as to generate 5-iodo-2-pyrimidone; performing a reaction on the 5-iodo-2-pyrimidone and 1-chloro-3,5-di(4-chlorbenzoyl)-2-deoxy-D-ribose so as to generate 1-[(3,5-di(4-chlorbenzoyl)-2-deoxy-beta-D-erythro-pentofuranose]-5-iodo-2-pyrimidone; and finally generating a target product by using the 1-[(3,5-di(4-chlorbenzoyl)-2-deoxy-beta-D-erythro-pentofuranose]-5-iodo-2-pyrimidone. All intermediates are stable, the yield is high, andthe method is suitable for industrial production.

1-(2-Deoxy-β-D-ribofuranosyl)-5-bromo-2-pyrimidinone (BrPdR) and 1-(2-deoxy-β-D-ribofuranosyl)-5-iodo-2-pyrimidinone (IPdR) have been synthesized by condensation of the appropriate silylated bases 2a and 2b, respectively, with 3,5-bis-O-(p-chlorobenzoyl)-2-deoxy-α-D-ribofuranosyl chloride (8) in 1,2-dichloroethane, in the presence of SnCl4, followed by separation of the anomeric blocked nucleosides via column chromatography and subsequent deprotection with methanolic ammonia.Both BrPdR and IPdR exhibited significant antiherpes activities against various strains of HSV-1 and HSV-2, the latter compound (IPdR) showing the higher activity as well as the stronger binding to the virus-specific thimidine kinase.
