The opticalresolution of (RS)-pantolactone (1) is carried out throughformation of diastereoisomeric amides. These are separated by a single hot washing with CH2C12 or CHC13. The used asymmetric amine, (1R)-3-endo-aminoborneol (4), is readily accessible and can be recovered almost quantitatively after resolution.
