  摘要：

  Abstractmagnified imageBy attaching (methyl)‐ or (difluoromethyl)‐phosphonate groups to the 1‐positions of ethene, cyclopentene or benzene, and attaching 1‐(methyl)‐5‐chlorouracil or 1‐(methyl)thymine groups to the corresponding 2‐positions, compounds 1–5 were prepared as potential inhibitors of recombinant human thymidine phosphorylase (TP). The products were designed to mimic the interatomic distance (ca. 3.41 Å) between the incoming phosphate and leaving pyrimidine groups at the transition state for the putative SN2 mechanism of TP. Free rotation around the (unsaturated‐CH2)–pyrimidine bonds in 1–5 enabled a span of ca. 2.40–4.40 Å between the CH2 or CF2 C‐atoms in the phosphonates and N(1) of the pyrimidines to be covered. The products were found to be ineffective inhibitors, and some reasons for this are given.
