Abstract
The chiral differentiation of the enantiomers of 2‐methylbutanoic acid, 2‐methylpentanoic acid and 2‐methylhexanoic acid was achieved by diastereomeric derivatization with R‐( – )‐pantolactone. GC separation on achiral DB‐1, DB‐1701 and DB‐WAX capillary columns as well as 1H‐ and 13C‐NMR enantiodiscrimination were obtained, affording good resolution and quantitative evaluation of enantiomer composition. The method applied to 2‐methylbutanoic acid present in the aromatic fraction extracted from cultivated strawberry (Fragaria vesca) indicated a high enantiomeric excess of the S‐isomer.
