3-Isopurine nucleosides, namely 3-(ribofuranosyl)purine nucleosides, are interesting owing to their potential biological activity and as components of modified oligonucleotides. A regio- and stereocontrolled method was developed for the synthesis of β-2′-deoxy-3-isopurine nucleosides using the intramolecular glycosylation protocol. The availability of this method was shown by the first chemical synthesis

Abstract The stereocontrolledsynthesis of 2′-deoxynucleoside analogs was explored by intramolecular glycosylation of pyridazine, pyrazines and triazines. These heterocycles were temporarily connected to the 5-O position in 1-thioglycoside via ethereal linkage.
