Title:
OLIGONUCLEOTIDE PRODUCTION METHOD, AND NUCLEOSIDE, NUCLEOTIDE, OR OLIGONUCLEOTIDE
Document Type and Number:
WIPO Patent Application WO/2017/104836
Kind Code:
A1
Abstract:
The present invention provides an oligonucleotide production method that includes: (1) a step in which a reaction liquid comprising a phosphite triester body (c) is obtained by condensing, in a nonpolar solvent, a nucleoside, nucleotide, or oligonucleotide (a) in which the 5'-hydroxyl group is not protected and a nucleoside, nucleotide, or oligonucleotide (b) in which the 5'-hydroxyl group is protected; (3) a step in which the phosphite triester body (c) is oxidized or sulfurized and a reaction liquid is obtained that comprises an oligonucleotide (d) in which the 5'-hydroxyl group is protected; (4) a step in which the oligonucleotide (d) is deprotected and a reaction liquid is obtained that comprises an oligonucleotide (e) in which the 5'-hydroxyl group is not protected; and (6) a step in which a polar solvent is added to the reaction liquid comprising the oligonucleotide (e), and the oligonucleotide (e) is purified by solid-liquid separation or extraction.
