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.

The acyclic nucleotide analogue (R,S)-9-[1-(2-hydroxyethylthio)-2-phosphonylethyl] adenine [HETPEA, 4] was prepared by coupling the adenine potassium salt with diethyl ethynylphosphonate followed by condensation of the product with 2-mercaptoethanol.

Conjugate addition of an anionic nucleophile (nucleobase) to an active triple bond (alpha, beta unsaturated carboxylate or phosphonate) was used for preparing alpha-ethenyl carboxylate or phosphonate derivatives of purines and pyrimidines.
Synthesis of (Z) and (E) α-alkenyl phosphonic acid derivatives of purines and pyrimidines
(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.
