  Synthesis of 3′-ethynylthymidine, 3′-vinylthymidine and 3′-bromovinylthymidine as potential antiviral agents

  摘要：

  The synthesis of three novel 3'-unsaturated carbon analogues of AZT and FLT is described. The key step in the synthesis is a Cu(I)- catalyzed addition of vinylmagnesium bromide to a 2,3-unsaturated lactone, followed by, in the case of compounds 2 and 3, elimination reactions of a dibromo-compound.
