7-Deaza Isosters of 2′-Deoxyxanthosine and 2′-Deoxyspongosine – Synthesis via Glycosylation of 2,4-Dichloro-7H-pyrrolo<2,3-d>pyrimidine

Compound 5a was obtained by glycosylation of 2,4-dichloro-7H-pyrrolo<2,3-d>pyrimidine (3b) with the halogenose 4.Due to the reactivity of the chromophore halogens removal of the toluoyl residues by sodium methoxide resulted in rapid displacement of the chloro substituents which prevented the isolation of the free deoxyriboside of 3b and led to the 2,4-dimethoxynucleoside 7.
