摘要描述了全部四种脱氧氟-α-d-吡喃葡萄糖基磷酸酯的合成。确定了其酸催化水解的速率常数,并且显示出氟取代在降低速率方面具有显著作用,特别是当取代邻近异头中心时。在25℃下在m HClO 4中测量的相对速率常数对于α-d-吡喃葡萄糖基磷酸酯和2-,3-,4-和6-脱氧氟衍生物分别为60.30:1.00:7.05:3.97:16.5。详细研究了2-脱氧-2-氟-α-d-吡喃葡萄糖基磷酸酯的水解,确定了4.1 eu(m反应物)和113.5 kJ.mol -1的活化熵和焓。在60°m HClO 4中的溶液中,研究了其水解的pH依赖性,并测定了单阴离子水解的速率常数(k M = 1。因此,提取了88×10 -6 s -1)和中性(k N = 6.23×10 -5 s -1)的物种。如所预期的,单阴离子的水解不受氟取代的显着影响。根据这些发现,合理化了几种机械上不同的酶利用这些氟化底物的能力或无能为力。

substitution by chain extension through an amide linkage. Functionalized congeners containing terminal 2-acylaminoethylamides prepared by this strategy retained P2Y14 activity, and molecular modeling predicted close proximity of this chain to the second extracellular loop of the receptor. In addition, replacement of glucose with other sugars did not diminish P2Y14 potency. For example, the [5′′]ribose derivative

glucopyranose analogues at positions C‐2, C‐3, C‐4, and C‐6. This systematic investigation allowed us to perform direct comparison of 19F resonances of fluorinatedglucoseanalogues and also to determine their lipophilicities. Compounds with a fluorine atom at C‐6 are usually the most hydrophilic, whereas those with vicinal polyfluorinated motifs are the most lipophilic. Finally, the solvation energies
