    Description / Table of Contents: Investigation of Chromatographic Resolutions of Racemates, VII Preparative Resolutions on Optically Active PolyamidesThe optically active polyamides 1, 2a and b enable optical resolutions of racemates of α-substituted 2-phenylacetamides (3a-g), mandelic acid derivatives (4a-c), N-substituted acetamides (5a-d. 6, 7), N-acylamino acid esters (8a-h), and benzoin derivatives (9a-c). The amide 5c was resolved on a preparative scale yielding both optically pure enantiomers.
    Notes: Die optisch aktiven Polyamide 1, 2a und b trennen Racemate von α-substituierten 2-Phenylacetamiden (3a-g), Mandelsäurederivaten (4a-c), N-substituierten Acetamiden (5a-d, 6, 7), N-Acylaminosäureestern (8a-h) und Benzoinderivaten (9a-c). Das Amid 5c wurde im präparativen Maßstab in beide optisch reinen Enantiomeren aufgetrennt.

    Description / Table of Contents: Investigation of Chromatographic Resolutions of Racemates, VI. Polymeric Amino Acid Derivatives as Optically Active AdsorbensStarting with optically active amino acids, the polyacrylamides 3a-h, 5a-d and 6a, b the polymethacrylamides 8a-c and the polyacrylic ester 6f were synthesized. The separation efficiencies of these polymers were determined by chromatography of racemic mandelic acid and mandelamide, respectively. The best separations of the enantiomers of both racemates were observed on the phenylalanine derivatives 3e and 5a.
    Notes: Die Polyacrylamide 3a-h, 5a-d und 6a, b die Polymethacrylamide 8a-c und der Polyacrylsäureester 6f wurden aus optisch aktiven Aminosäurederivaten hergestellt und auf ihre Trennwirkung durch Chromatographie racem. Mandelsäure sowie racem. Mandelamids geprüft. Die beste Trennung der Enantiomeren beider Racemate wurde an den Phenylalaninderivaten 3e und 5a beobachtet.

    Chloroquin-Enantiomere durch chromatographische Racemattrennung und Synthese (1978)
    Weinheim : Wiley-Blackwell

    Notes: Chloroquine Enantiomers by Chromatographic Resolution and SynthesisThe chromatographic resolution of the antimalarial drug chloroquine (1) on an optically active polyamide is described. The results reveal that the optical purity of chloroquine formerly resolved with d-bromocamphorsulfonic acid was 12% only. A facile synthesis of the enantiomers via the optically active diamine 4 is given.
