Pantothenate synthetase (PS), a member of adenosine acylation enzyme family, was the new target of anti-tuberculosis drug development. Employing bioisostere principle, 5'-O-{[(R)-2-hydroxy-3,3-dimethylbutanoyl]sulfamoyl}-2'-deoxy-2'-fluoroadenosine (1), a mimic of the PS catalyzed reaction intermediate, was rational designed by substituting the 2'-hydroxyl group of intermediate sugar ring with fluorine. This compound was synthesized using D-tertiary leucine and vidarabine as the starting materials by 9 steps of reaction, and its structure was fully characterized by 1H NMR, 13C NMR and HR-MS techniques.

Key words: fluorinated adenosine derivative, pantothenate synthetase, anti-tuberculosis, total synthesis
