✦ Synopsis

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.

4-methoxy and 4-(2-trimethylsilylethoxy)pyrimidine bases were attached to the 5position of the phenyl 2,3-dideoxy-l-seleno-glycero-pentofuranoside moiety. The presence of the silyl protecting group in the base is necessary to lead to neutral 13-anhydro nucleosides by inlramolecular glycosylafion. Th
