Synthesis of novel 2'-deoxy type trans-3',4'-bridged nucleic acid.
We newly designed and synthesized a 2'-deoxy type trans-3',4'-bridged nucleic acid (trans-3',4'-BNA) analogues bearing a 4,7-dioxabicyclo[4.3.0]nonane structure. The synthesis of the trans-3',4'-BNA was carried out successfully from thymidine over 21 steps. The structure of trans-3',4'-BNA was confirmed by x-ray crystallographic analysis, indicating that the furanose ring has a typical S-type conformation with C(3')-exo puckering.
