Nucleoside Chemical Synthesis Service
Characterization of Nucleosides
Nucleosides are widely found in nature and they are closely related to life activities. The use of nucleosides is highly specialized, and they are indispensable raw materials in biomedical research, as well as basic elements in the preparation of biological products. For example, nucleosides are widely used as antitumors, antiviral small molecule drugs, and nucleic acid drugs. Meanwhile, nucleoside derivatives are also vital raw materials for gene sequencing kits. Modification of nucleoside bases or sugar rings is a common strategy to enhance the pharmacokinetic and pharmacodynamic properties of nucleoside molecules, reduce the immunogenicity of nucleic acid drugs, and improve their stability. In addition, nucleosides have important applications in molecular biology, gene cloning, and DNA microarrays. Thus, nucleosides are expected to be the next generation of drugs with important roles after sulfonamides and antibiotics. Based on the numerous advantages of nucleosides, a comprehensive production study of nucleosides is necessary.
Key Technologies
Based on our nucleoside chemical synthesis service, we leverage advanced chemical methods including total synthesis and precise structural modification of nucleoside backbones, enhanced by microwave-assisted technology to accelerate reactions and improve efficiency, followed by rigorous characterization using NMR, LC-MS, HPLC, and thermal analysis to deliver high-quality, tailor-made nucleosides for research and development.
Precision-Scale: Nucleoside Synthesis, Perfected
There are numerous routes for the production of nucleosides, of which chemical methods are already a well-established synthetic route. At CD BioGlyco, we offer a full range of chemical synthesis services. Specifically, we offer chemical production services including, but not limited to:
- Total synthesis of nucleosides
- Backbone synthesis of nucleosides
- Derivative synthesis of nucleosides
- Chemical modification of nucleosides
During the chemical synthesis process, we provide microwaves to improve the efficiency of the synthesis.
In addition to nucleoside synthesis services, we also provide product analysis services. Specific services include, but are not limited to, structural characterization of the products (NMR hydrogen spectroscopy, liquid-mass spectrometry, high-performance liquid chromatography, XRD, etc.) and performance testing (thermogravimetric analysis, etc.).

Workflow
Based on our expertise in nucleoside chemistry and the latest advancements in the field, we synthesize nucleosides and their analogs through a strategic blend of chemical approaches.
- Sugar Activation
Protect ribose/deoxyribose at C1 with acetyl or benzoyl groups, while selectively shielding C2'/C3'/C5'-OH with TBDMS or acetyl. Activate C1 via oxocarbenium intermediates using Lewis acids (e.g., SnCl4, TMSOTf).
- Base Coupling
Silicon-protected bases (e.g., bis-TMS-adenine) attack the activated sugar, yielding β-configured nucleosides (natural stereochemistry) with high selectivity.
- Deprotection
Remove protecting groups under mild acidic/basic conditions (e.g., NH3/MeOH for acetyl, HF for TBDMS).

Results: The authors reviewed existing chemical methods for synthesizing β-nucleosides via N-glycosylation of nucleobases. They conducted a comprehensive sustainability assessment, calculating route environmental factors (E-factors) for over 80 synthetic pathways from unprotected starting materials. Their analysis revealed that despite often achieving high glycosylation yields, most methods suffer from inefficient routes requiring multiple protecting groups and extensive chromatography. The study identified key inefficiencies: excessive solvent usage (especially from chromatography), lengthy multi-step routes, and heavy reliance on protecting groups. The authors conclude that future efforts should prioritize non-chromatographic purification, shorter synthetic routes, higher substrate concentrations, and potentially biocatalytic methods to enable greener nucleoside synthesis.
