Nucleic-Acid Analogues with Constraint Conformational Flexibility in the Sugar-Phosphate Backbone ('Bicyclo-DNA'), Part 1. Preparation of (3'S,5'R)-2'-Deoxy-3',5'-ethano-αβ-D-ribonucleosides ('Bicyclonucleosides')

Tarkoey, Markus,Bolli, Martin,Schweizer, Bernd,Leumann, Christian

, p. 481 - 510 (1993)

We describe the synthesis of 2'-deoxy-3',5'-ethano-D-ribonucleosides 1-8 (=(5',8'-dihydroxy-2'-oxabicyclooct-3'-yl)purines or -pyrimidines) of the nucleobases adenine, thymine, cytosine, and guanine.They differ from natural 2'-deoxyribonucleosides
