A stereoselective synthesis of 3'-O-((R,R,R)-trimethylsilatranyl)thymidine (R,R,R-1) and synthesis of 3'-O-silatranylthymidine (5) via an improved silatranylation procedure using tetrakis(dimethylamino)silane are reported. Diastereomeric mixture 1 showed more activity than R,R,R-1 or 5 in a primary anticancer screen against breast, CNS, and lung cell lines; demonstrating the import of the configuration
