The pure enantiomers of felodipine, 1, have been synthesized by chromatographic separation of diastereomeric esters with (R)-l-(p-toluenesulfonyl)-3-trityloxypropan-2-ol, 3, as an easily removable chiral auxiliary. Absolute configurations have been deduced via X-ray crystallography on a (R)-mandelic
