Sulfur-Transfer Reagents Xanthane Hydride and DDTT for Oligonucleotide Phosphorothioate Synthesis
Share
Xanthane Hydride (X0001) and DDTT (D5920) are sulfur-transfer reagents for the synthesis of oligonucleotide phosphorothioates via the phosphoramidite method. Xanthane Hydride is used as a sulfur-transfer reagent and as a solution for DNA/RNA synthesizers, at 0.02 M in acetonitrile/pyridine (9:1) or 0.20 M in pyridine.³) ⁵) Its key advantage is that it does not yield oxidizing substances, carbon disulfide, or cyanamide as additional reaction products, which can cause side reactions and generate toxic substances. DDTT shares this advantage, and additionally has a dmf-protected amino group compared with X0001. It is expected to be more stable than X0001 in solution.⁶) Beaucage reagent (B3125) and bis(phenylacetyl) disulfide (B3623) are also widely used for similar purposes.¹) ²)
