Synthesis of (Z) and (E) α-alkenyl phosphonic acid derivatives of purines and pyrimidines
摘要:
(Z) and (E)-2-(purin-9-yl/pyrimidin-1-yl)ethylen-1-ylphosphonic acid 10-18 were synthetized by Michael addition of heterocyclic base with the diethylethynylphosphonate and deprotection of the acyclic nucleoside phosphonate with bromotrimethylsilane.

The E- and Z- phosphonoalkenyl acyclonucleosides of uracil and thymine were synthesized under Michael addition conditions. Introduction of an alkyl, alkenyl or alkynyl group at the N-3 position of the pyrimidine moiety was accomplished using potassium carbonate in DMF.
嘧啶部分的N-3位引入烷基、烯基或炔基是通过在DMF中使用碳酸钾实现的。

Synthesis of new acyclic nucleoside phosphonic acids by Michael addition
Newacyclicnucleosidephosphonicacids in the purine and pyrimidine series were prepared via one step by Michaeladdition. These compounds are the first reported acyclonucleosides enamines which incorporate the α, β-unsaturated phosphonicacid as a phosphate mimic.
