New chiral stationary phases of polydimethylsiloxane anchored with (S)-(Γ)-t-leucine derivatives were provided for use in enantiomer separation of pharmaceuticals by capillary gas chromatography. Fifteen pharmaceuticals were separated into their enantiomeric pairs by converting them into pentafluoro
fungal strains Tolypocladium inflatum, T. geodes, and T. terricola, which differ only by their N-acylpipecolic acid terminus). According to the primary amino acids found (1 Gly, 1 p-Ala, 1 L-Ala, 2 L-Leu and about 9 a-aminoisobutyric acid), it can be concluded, that tolypin represents a mixture of p
