Applications of Azotation in Structural Modification

Nitrogen atoms are important elements in bases that can be introduced, replaced, or modified to change the nature and function of the nucleoside. Azotation modification involves a series of chemical reactions, including the introduction of amino groups, carbamate groups, nitro groups, etc., to bases. In nucleoside modification, azotation is commonly used to introduce amino groups. For example, using nitrite or other nitrogen-containing reagents to react with it to cause a substitution reaction, an amino group is introduced into the molecule to form the corresponding amino-modified products. This modification method has an important application value in abiotic synthesis and can be used to synthesize a variety of nucleosides and nucleotide derivatives with specific functions or properties to meet the needs of drug discovery and development, chemical biology research, and materials science. It meets the needs of drug discovery, chemical biology research, and materials science.

Base-based Azotation Modification Service at CD BioGlyco

CD BioGlyco specializes in the field of Nucleoside & Nucleotide Modification and provides high-quality base-based Halogenation, N-conjugation, and azotation modification services. Through azotation reactions, we introduce nitrogen groups to realize changes in their structure and function. The specific azotation modification services we offer include the following:

• Under alkaline conditions, we react electrophilic nitroso reagents such as nitrites or nitrosamines with nucleosides or nucleotides. It is modified by the substitution reaction of the electrophilic nitroso reagent with the nitrogen-containing basic site.
• We use some metal catalysts, such as palladium or copper catalysts, to induce the reaction of C-H bonds in nucleosides with a nitrogen source to form new C-N bonds. This improves the selectivity and reactivity of the modification and can be performed under mild reaction conditions.
• It is modified by reaction with a nucleophilic reagent, such as an amine, in which the amino group in the nucleoside or nucleotide is replaced by a new amine compound.
