A New Approach to the Synthesis of Acyclic Nucleotide Phosphonate Analogues with Triple or Double Bonds

[摘要]：On the basis of new methodology to design the phosphonate analogues of nucleotides, the first series of acyclic nucleotides possessing a triple bond in the carbon skeleton were prepared by coupling diethyl 4-chlorobuta-1,2-dienylphosphonate with the corresponding purine or pyrimidine nucleic bases under base-catalyzed alkylation conditions.
