| Hazard Information | Back Directory | [Description]
2'-O-(2-Methoxyethyl)-guanosine is a guanosine derivative isolated from the reaction of 2-aminoadenosine with methylsulfonyl chloride. 2'-O-(2-Methoxyethyl)-guanosine can be used as a building block for cross-linking oligonucleotides. | [Uses]
A guanosine derivative as building blocks for cross-linking oligonucleotides. | [Definition]
2'-O-(2-Methoxyethyl)guanosine, a 2′-O-methoxyethyl-modified nucleoside, can be produced by enzymatic conversion (adenosine deaminase) from 2′-O-(2-methoxyethyl)-2,6-diaminopurine riboside.
| [Synthesis]
Compound 7 (50 mg, 0.086 mmol) was used as a starting material, which was dissolved in a mixed solvent of THF and water, and TBAF (1 M solution of THF, 0.009 mL, 0.009 mmol) was added at 25 °C. The reaction mixture was warmed up to 35 °C with continuous stirring for 5 hours. Upon completion of the reaction, the solvent was removed by distillation under reduced pressure. The residue was purified by filtration through a short silica gel column using a dichloromethane solution of 10% methanol as eluent to afford the target product 2'-O-MOE G (compound 8) (28 mg, 0.082 mmol, 97% yield). The 1H NMR (400 MHz, DMSO) data of compound 8 were as follows: δ 10.68 (s, 1H), 7.95 (s, 1H), 6.50 (s, 2H), 5.78 (d, J = 6.0 Hz, 1H), 5.08 (d, J = 5.2 Hz, 2H), 4.33 (d, J = 6.0 Hz, 1H), 4.23 (d, J = 3.2 Hz, 1H), 3.88 (d, J = 3.2 Hz, 1H), 3.65 (m, 3H), 3.52-3.57 (m, 2H), 3.35 (s, 3H), 3.38-3.40 (m, 1H). | [References]
