Synthesis of the Nucleotide Analogue: (R,S)-9-[1-(2-Hydroxyethylthio)-2-phosphonylethyl] Adenine
摘要:
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.
Synthesis of Acycloalkenyl Derivatives of Pyrimidines and Purines
摘要:
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.
