✦ Synopsis


Nucleic-Acid Analogues with Constraint Conformational Flexibility in the Sugar-Phosphate Backbone 'Tricyclo-DNA'. Part 1. Preparation of [(5'R,6'R)-2'-Deoxy-3',5'-ethano-5',6'-methano-β-D-ribofuranosyl] thymine and -adenine, and the Corresponding Phosphoramidites for Oligonucleotide Synthesis.

-An efficient synthesis of the tricyclonucleosides (VIII) and (IX) containing the bases adenine and thymine as well as that of building blocks (X) for oligonucleotide preparation is described. -
