Synthesis of 4-formyl-4-imidazolin-2-one nucleosides, isomers of uridine and 2'-deoxyuridine. | LitMetric
The syntheses of the ribo- and deoxyribonucleoside derivatives of 4-formyl-4-imidazolin-2-one, isosteric isomers of uridine and 2'-deoxyuridine, respectively, were carried out by ring contraction of the corresponding 5-bromouracil nucleosides, followed by conversion of the carboxyl side-chain of the products to the respective carboxaldehyde derivatives.
