Synthesis of Thymidine Dimers from 5 '-O-Aminothymidine

[摘要]：The synthesis of modified oligonucleotides is of great importance for various therapeutic and diagnostic applications. The facile secondary structure formation of N-oxyamide-linked peptide analogues and the high nucleophilicity of the aminooxy function prompted us to prepare O-amino nucleoside derived dinucleosides. Herein, the efficient synthesis of three novel thymidine dimers with N-oxyamide, oxime and oxyamine linkages via a convergent approach from a common 5'-O-aminothymidine is reported.
