Abstract
| - Bis- and trisuracil nucleosides, in which the nucleobases are anchored to isoxazoline ring-fused 11-, 12-,and 16-membered macrooxacycles, were synthesized by nucleosidation of 1,2-isopropylidenefuranosering-fused macrocycles. The nucleosides exhibited spherical and fiber-like morphologies in water. Inone case, the morphology was significantly altered by complexation with an adenine nucleoside viacomplementary base pairing.
