Oxidation of Thymines by Peroxosulfate Ions in Water

Article abstract of DOI:10.1021/jo00250a003

Oxidation of thymines by sodium peroxodisulfate in water at 85 deg C gave the corresponding 5-(hydroxymethyl)uracils and 5-formyluracils.The reaction may proceed via thymine cation radicals.On the other hand, oxidation of thymines by potassium peroxomonosulfate in water gave the corresponding cis-5,6-dihydroxy-5,6-dihydrothymines and 5-hydroxy-5-methylbarbituric acids.Furthermore, treatment of thymine with both potassium peroxomonosulfate and hydrogen peroxide in water gave cis-6-hydroperoxy-5-hydroxy-5,6-dihydrothymine.
