Al~tract: A pyrimidine moiety was tethered at the 3'-~-position of D-threo-furanosides. By carefully controlling the reaction conditions, pyrimidine bases can be delivered to the anomeric center to give of ~-pyrimidine nucleosides in good yield and with complete stereocontrol.

## Abstract Nucleobase‐anion glycosylation of 6‐(methylthio)‐2‐azapurine (1) with 2‐deoxy‐3,5‐di‐__O__‐(p‐toluoyl)‐α‐D‐erythro‐pentofuranosyl chloride (2) yields the 2′‐deoxy‐β‐D‐ribofuranosides 3–5 stereoselectively. The distribution of regioisomers is as follows: N‐9 (32%); N‐2 (30%), and N‐7 (7%
