Substituted purine and deazapurine nucleosides are of great interest in medicinal chemistry. Furthermore, 3′-deoxynucleosides exhibit a number of biological activities. In this research the coupling of 2,6-dichloro-1- or 3-deazapurine with protected 3′-deoxyribose is reported. Depending upon coupling conditions and base structure, different anomeric and isomeric mixtures have been obtained. Extensive studies, utilizing chemical and physical methods, have been performed to assign the correct configuration to the resulting nucleosides.

Abstract
Substituted purine and deazapurine nucleosides are of great interest in medicinal chemistry. Furthermore, 3′-deoxynucleosides exhibit a number of biological activities. In this research the coupling of 2,6-dichloro-1- or 3-deazapurine with protected 3′-deoxyribose is reported. Depending upon coupling conditions and base structure, different anomeric and isomeric mixtures have been obtained. Extensive studies, utilizing chemical and physical methods, have been performed to assign the correct configuration to the resulting nucleosides.File in questo prodotto:
