  • Publication number: 20220372060
    Abstract: Disclosed are a 5?-modified nucleoside and a nucleotide using the same. The nucleoside of the present invention is represented by the formula (I) below. The 5?-modified nucleoside of the present invention is usable as a substitute for a phosphorothioate-modified nucleic acid, which has a risk of, for example, accumulation in a specific organ. The 5?-modified nucleoside also has excellent industrial productivity because a diastereomer separation step is not involved in the production process thereof.
