The synthesis of two riboside-containing arsenic compounds, methyl-2,3-O-isopropylidene-5-dimethyl-arsinoyl-β-d-ribofuranoside and methyl-2,3-O-isopropylidene-5-deoxy-5-dimethyl-thioarsinoyl-β-d- ribofuranoside is presented in this paper. Intermediates and final products of the synthesis were examined by gas chromatography and thin layer chromatography. The purity of the products was assessed by NMR spectroscopy. Trimethylsilylation was used to volatilise sugar compounds and thus use of the costly HPLC–MS technique was avoided. The results affirmed the presence of tautomers in case of arsenosugars.
Graphical abstractThe synthesis of two riboside-containing arsenic compounds, methyl-2,3-O-isopropylidene-5-dimethyl-arsinoyl-β-d-ribofuranoside and methyl-2,3-O-isopropylidene-5-deoxy-5-dimethyl-thioarsinoyl-β-d-ribofuranoside is presented in this paper. Trimethylsilylation was used to volatilise the sugar compounds. GC, TLC and NMR spectroscopy were used for the identification and characterisation of the synthesised intermediates and products. The results affirmed the presence of tautomers in the case of the arsenosugars.Figure optionsDownload full-size imageDownload as PowerPoint slide
