A Useful Method for the Synthesis of β-2′,3′-Dideoxynucleosides via a Thioglycoside

Abstract
A series of the protected β-2′,3′-dideoxypyrimidine nucleosides are synthesized stereoselectively by the coupling of phenyl 5-O-(tert-butyldiphenylsilyl)-2,3-dideoxy-1-thio-D-glycero-pentofuranoside with silyl derivatives of nucleoside bases in the presence of N-bromosuccinimide at -78 °C.
