  Nucleoside 5′-C-phosphonates: reactivity of the α-hydroxyphosphonate moiety

  摘要：

  We found that various dialkyl phosphites, dialkyl trimethylsilyl phosphites, and tris-trimethylsilyl phosphite reacted smoothly with nucleoside 5'-aldehydes to afford epimeric nucleoside 5'-C-phosphonates in high yields. A number of these compounds in both the 2'-deoxyribo and ribo series were prepared. In the case of 2'-deoxythymidine-5'-aldehyde, a thorough study was made on the influence of the 5'-hydroxyl protecting group, type of phosphite, base, and solvent, on the yield and epimeric ratio of the resulting 5'-hydroxyphosphonates. Partial stereoselectivity in favour of either R or S epimers was observed. An attempt to transform the alpha-hydroxyl of the phosphonate moiety into a halo or azido moiety was not Successful. Only intramolecular substitution reaction of the mesyloxy group for an alkoxy residue of the 2-hydroxyethyl ester took place in a low yield. (c) 2006 Elsevier Ltd. All rights reserved.

  呋喃呋喃糖5-（α-羟基膦酸酯）的氧化裂解：生成基于呋喃呋喃糖的核苷膦酸的途径

  摘要：

  我们在这里报告在强酸性和中性条件下，高碘酸根阴离子对（5 R）-和（5 S）-呋喃核糖基-5- C-膦酸酯衍生物的氧化裂解。在这两种情况下，仅（5 R）构型的化合物进行了预期的氧化反应，并提供了所需的（4 R）-呋喃呋喃糖基膦酸酯，而第二种差向异构体（5 S）-核呋喃糖基-5- C-膦酸酯未提供相应的（4S）-呋喃呋喃糖基膦酸酯衍生物。差向异构体对氧化裂解的这种不同行为是一种重要现象。所得（4 R）-呋喃呋喃糖基膦酸酯通过经典的核苷化反应用于制备5'-磷酸腺苷的膦酸酯模拟物。然而，受保护的缩短的AMP类似物与腺苷衍生物的缩合仅提供了2'，5'-连接的ApA类似物。修饰的2'-5'ApA与polyU杂交的研究表明，它具有形成稳定的三链体样复合物的能力，类似于天然2'-5'r（ApA）和3'-5'r（ApA）。NMR光谱研究表明，修饰的2'-5'ApA的膦酸核苷酸单元的赤呋喃糖部分主要为C2'-内构象，这是B-DNA的特征。

  intermediates were deprotected to give the 6'-chloro 3a, 6'-bromo 3b, and 6'-iodo 3c acetylenic nucleoside analogues. Iodo compound 3c appears to inactivate S-adenosyl-L-homocysteine hydrolase by a type I ("cofactor depletion") mechanism since complete reduction of enzyme-bound NAD+ to NADH was observed and no release of adenine or iodide ion was detected. In contrast, incubation of the enzyme with the chloro 3a

  Moffatt oxidation of 2',3'-O-isopropylideneuridine (1a) and treatment of the crude 5'-aldehyde with formylmethylene-stabilized Wittig reagent gave the vinylogously extended 7'-aldehyde2a. Condensation of 2a with ethoxycarbonyl- or dibromomethylene phosphorane reagents gave the conjugated dienes 6a and 4a, respectively.

  Treatment of the protected ribose or xylose 5-aldehyde with sulfonyl-stabilized fluorophosphonate gave (fluoro)vinyl sulfones. Stannyldesulfonylation followed by iododestannylation afforded 5,6-dideoxy-6-fluoro-6-iodo-D-ribo or xylo-hex-5-enofuranoses. Coupling of the hexenofuranoses with alkylzinc bromides gave 10-carbon ribosyl- and xylosylhomocysteine analogues incorporating a fluoroalkene. The fluoroalkenyl and alkenyl analogues were evaluated for inhibition of Bacillus subtilis S-ribosyl-homocysteinase (LuxS). One of the compounds, 3,5,6-trideoxy-6-fluoro-D-erythro-hex-5-enofuranose, acted as a competitive inhibitor of moderate potency (K(I) = 96 mu M). (C) 2008 Elsevier Ltd. All rights reserved.
