title: Design and racemic synthesis of conformationally restricted carbocyclic pyrimidine nucleoside analogs based on the structure of the L-nucleoside residue in heterochiral DNA.
abstract: Carbocyclic pyrimidine nucleoside analogs which have restricted glycosidic conformation at chi approximately 180 degrees were designed, based on the conformational features of the L-nucleotide residue in heterochiral DNA, and synthesized. The synthesis of (+/-)-carbocyclic 6,6'-O-cyclo-2'-deoxyuridine was achieved via bromination and subsequent intramolecular cyclization of carbocyclic 6'beta-hydroxy-2'-deoxyuridine. (+/-)-Carbocyclic 6,6'-O-cyclo-2'-deoxycytidine was synthesized from protected carbocyclic 6,6'-O-cyclo-2'-deoxyuridine via the 4-triazole intermediate.
