title: Synthesis of 2'-deoxy-6,2'-methano-pyrimidine nucleosides and optical properties of pyrimidine C-cyclonucleosides.
abstract: 2'-Deoxy-6,2'-methano derivatives of uridine, cytidine, and 4-thiouridine were synthesized by the Peterson olefination of a ketosugar with a pyrimidine followed by an intramolecular glycosylation reaction. CD-spectra of these cyclonucleosides together with other pyrimidine C-cyclonucleosides were given.
