✦ Synopsis
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 peptides closely related or almost identical to effrapeptins [20, 211.

New chiral stationary phases of polydimethylsiloxane anchored with (S)-(À)-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
