  The Synthesis of Some 5-Substituted and 5,6-Disubstituted 2′-Deoxyuridines

  摘要：

  5-Alkyl(cycloalkyl)-2'-deoxyuridines VIa-VIf were synthesised in high yields by condensation of the corresponding silylated bases with 2-deoxy-3,5-di-O-p-toluoyl-D-erythro-pentosyl chloride in chloroform and subsequent deblocking with sodium methoxide in methanol. The beta-configuration, anti-glycosidic conformation and C2'-endo (S) sugar pucker of all of these compounds has been established from their H-1 NMR, C-13 NMR, UV and mass spectra. Under the same conditions, the condensation of silylated 5,6-trimethyleneuracil, resulted in 1:2/alpha:beta anomeric mixture (overall yield 71%) and syn-conformation of the 5,6-trimethylene-2'-deoxyuridine [Xg]. The results of the condensation of the silylated 5,6-dimethyluracil are discussed as well. No significant antiviral activity has been found in testing the synthesised compounds against a range of herpes, influenza and HIV-1 viruses.

  Bis(trimethylsilyl)pyrimidine bases were treated directly with 1, 3-dioxolane (or 2-methyl-1, 3-dioxolane), chlorotrimethylsilane and a metal iodide, such as KI or NaI, in acetonitrile at room temperature to afford acylopyrimidine derivatives, including 2-thiopyrimidine derivatives, in good yields. Introduction of an acyclic chain into 2-thiopyrimidine bases, however, necessitated the use of 2 eq of the reagents.

  In order to study structure-activity relationships between antiherpetic activity and the size of the C-5 alkyl substituents of 2'-fluoro-ara-U derivatives, six new nucleosides (1c-h) were synthesized. The 5-allyl analogue 1c was prepared by a Pd(II)-catalyzed reaction of 5-(chloromercuri)-1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracil with allyl chloride. Partial hydrogenation of 1c afforded the

• 5-Substituted UTP derivatives as P2Y2 receptor agonists
  作者：B Knoblauch

  DOI：10.1016/s0223-5234(99)00211-1

  日期：1999.10

  A series of 5-alkyl-substituted UTP derivatives, which had been synthesized previously with a moderate degree of purity, was resynthesized, purified, and characterized. Synthetic and purification procedures were optimized. New spectroscopic data, including C-13- and P-31 NMR data, are presented. Phosphorylation reactions yielded a number of side products, such as the 2'-, 3'-, and 5'-monophosphates, the 2',3'-cyclic monophosphates, and the 2',3'-cyclic phosphates of the 5'-triphosphates. Furthermore, raw products were contaminated with inorganic phosphates, including cyclometatriphosphate, phosphate, and pyrophosphate. The uracil nucleotides were investigated for their potency to increase intracellular calcium concentrations by stimulation of P2Y(2) receptors (P2Y(2)R) on NG108-15 cells, a mouse neuroblastoma x glioma cell line, and in human basal epithelial airway cells, including a cystic fibrosis (CF/T43) cell line. UTP exhibited EC50 values of ca. 1 mu M (in NG108-15 cells) and of 0.1 mu M (in CF/T43 cells), respectively. 5-Substituted UTP derivatives were agonists at the P2Y(2)R, but were less potent than UTP. 5-Ethyl-UTP, for example, exhibited an EC50 value of 99 mu M at P2Y(2)R of NG108-15 cells and proved to be a full agonist. With increasing volume of the 5-substituent of UTP derivatives, P2Y(2) activity decreased. (C) 1999 Editions scientifiques et medicales Elsevier SAS.

  The silylated pyrimidine bases IIa-d were condensed with the benzyl 3,5-di-O-benzyl-2-deoxy-1,4-ditkio-D-erythro-pentofuranoside III in acetonitrile under activation by N-iodosuccinimide, giving ca 1.5 : 1/alpha: beta anomeric mixtures of the blocked nucleosides IVa-d and Va-d. in yields of 55-88%. After the separation on a silica column the pure anomers were deprotected by BCl3 or TiCl4, providing the free nucleosides VIa-d and VIIa,c,d in moderate to good overall yields. The beta- or alpha-anomeric configuration, anti-glycosidic conformation and prevailing C2'-endo(S) thiosugar pucker in the synthesized compounds were established by the combined use of the H-1, C-13 NMR and X-ray crystallography.
