A Short Highly Stereoselective Synthesis of the Fluorinated Natural Product (2S,3S)‐4‐Fluorothreonine.

A three step stereoselective route to the fluorinated natural product (2S,3S)-4-fluorothreonine is described; the route is amenable to the preparation of (2S,3S)-4-fluoro[3- 2 H]threonine and (2S,3R)-[4,4,4- 2 H 3 ]threonine.
