title: Reaction of l-halogenoses with nitrogen nucleophiles in the presence of tert-amine. Synthesis of 2'-deoxyribofuranosyl and arabinofuranosyl pyrimidines.
abstract: Selective introduction of 2'-deoxyribofuranosyl and arabinofuranosyl moieties onto one of two nitrogen atoms in the pyrimidine ring was demonstrated by the reaction of 1-glycosyl chlorides with pyrimidines protected by the (octylthio)carbonyl group in the presence of tert-amine. Replacing pyrimidines by imidazole derivatives such as benzimidazole and theophylline as nucleophiles gave no nucleosides but orthoamide derivatives.
