Abstract

5-Carboxy-2'-deoxyuridine is a methyl oxidation product of thymidine. It can be formed by the menadione-mediated photosensitization of thymidine in aerated aqueous solution. Here in we present a new four-step synthesis of the 5-carboxy-2'-deoxyuridine phosphoramidite building block based on the alkaline hydrolysis of 5-trifluoromethyl-2'-deoxyuridine. The phosphoramidite derivative has been incorporated at defined sites into Oligonucleotides using the solid phase synthesis approach.
