## Abstract Fatty acids from blood serum lipids and fish oil preparations are derivatized with 2โaminoโ2โmethylโ1โpropanol to form 2โsubstituted 4,4โdimethyloxazolines. The derivatives are separated on a 25 m ร 0.25 mm FFAP column and identified by mass spectrometry using electron impact ionization
An alternative and cost effective route for the resolution in high ees (95-99%) of (:-~)-mandelicand (.+-)-2-(chlorophenoxy)propionic-acid derivatives is reported. The key step involves the covalent derivatization and separation of their diastereomeric amides with (R)-or (S)-cC-arylethylamines.
