Ring contraction and rearrangement of 4-thiofuranose derivatives observed during dast fluorination in the synthesis of L-2'-'up'-fluoro-4'- thiothymidine

Ring contraction and rearrangement of 4-thiofuranose derivatives were observed through the regioselective opening of the episulfonium ion formed during DAST fluorination in the synthesis of L-2'-'up'-fluoro-4'- thiothymidine.
