L-Proline, a resolution agent able to target both enantiomers of mandelic acid: an exciting case of stoichiometry controlled chiral resolution. | LitMetric

AI Article Synopsis

  • Researchers have discovered a new method for chiral resolution using L-proline, allowing for the separation of R- and S-enantiomers of mandelic acid from a racemic mixture.
  • This technique is innovative because it only requires changing the amounts of the resolving agent (stoichiometry) to achieve the separation.
  • The success of this method is attributed to the formation of diverse cocrystal systems between the L-proline and the mandelic acid enantiomers, marking a significant advancement in the field.

Article Abstract

We present a thought-provoking development in chiral resolution. Using a resolving agent of a given handedness, L-proline, we show that both R- and S-enantiomers of mandelic acid can be resolved from a racemic mixture simply by varying the stoichiometry. We are the first to report this specific feature, achieved by the existence of stoichiometrically diverse cocrystal systems between R- and S-mandelic acid and L-proline.
