Different approaches currently used to introduce the 5-hydroxymethyl moiety onto pyrimidine-based deoxynucleosides were reinvestigated. The oxidation of the methyl of thymidine followed by the reduction of the resulting formyl group allowed access to protected 5-hydroxymethyl-2’-deoxyuridine in a simple way and in good yields. Examples of application to the synthesis of relevant building blocks are
重新研究了目前用于将 5-羟甲基部分引入到基于
