A chiral synthesis of a series of hexahydroisobenzofuran (HIBF) nucleosides has been accomplished viaglycosylation of a stereo-defined (syn-isomer) sugar motif 16 with the appropriate silylated bases. All nucleoside analogs were obtained in 52–71% yield as a mixture of α- and β-anomeric products increasing the breadth of the novel nucleosides available for screening. The structure of the novel bicyclic
