Abstract
This chapter describes procedures for (1) the synthesis of six 2'-C,4'-C-ethyleneoxy-bridged thymidine phosphoramidites, i.e., methylene-EoDNA-T, (R)-Me-methylene-EoDNA-T, (S)-Me-methylene-EoDNA-T, EoDNA-T, (R)-Me-EoDNA-T, and (S)-Me-EoDNA-T phosphoramidites, (2) the introduction of the phosphoramidites into oligonucleotides, (3) UV-melting experiments of the duplexes of the modified oligonucleotides and complementary RNA, and (4) nuclease degradation experiments of the modified oligonucleotides.
