✦ Synopsis


2-Hydroxyoctadecanoic acid was resolved into D and L isomers as salts of 1-phenylethylamine enantiomers The diastereomers of phenylethylamides of 2-hydroxy fatty acids and the eorresponalng derivatives with protected hydroxy group (aeetyl, methyl, trifluoro-acetyl, tfimethylsilyl) are well separated by thin-layer or gas-liquid chromatography. This allows a simple microanalysis of configuration and optical purity of 2-hydroxy fatty acids. With this method 2-hydroxy fatty acids from sphingomyelin of the honey-bee were shown to belong exclusively to the D series.
