  • Title: Synthesis of phosphono-pyrimidine and -purine ribonucleosides.
    Author: Maruyama T, Kimura S, Horikawa M, Sato Y, Honjo M.
    Journal: Nucleic Acids Symp Ser; 1983; (12):43-5. PubMed ID: 6664871.
    Abstract:
    The reaction of the lithiated species of 2', 3', 5'-tri-O-protected uridines and 6-chloropurine ribonucleoside with diethyl chlorophosphate provided the corresponding diethyl phosphonate derivatives (III, IV and VIII). The Arbuzov-reaction of 2', 3', 5'-tri-O-protected 4-chloro-2(1H)-pyrimidinone ribonucleoside with triethyl phosphite afforded the diethyl phosphonate derivative (VI).
