  • Publication number: 20200331945
    Abstract: The present invention pertains to a method for synthesizing a ribonucleic acid H-phosphonate monomer, and a method for performing oligonucleotide synthesis in which said monomer is used. The present invention pertains to a method for manufacturing an inexpensively manufacturable H-phosphonate nucleoside derivative in which selective protection is provided to position 2? of a ribonucleoside monomer required in RNA oligonucleotide synthesis. The present invention is characterized in that: hydroxyl groups in position 2? and position 3?, which have slightly different reactivity, are caused to react with an aromatic acyl halide at low temperature to selectively esterify position 2?; and subsequently the hydroxyl group at position 3? in one pot is captured by a phosphityl group to prevent position 2? and position 3? transfer of the acyl group.
