    Enantiomeric resolution by HPLC of axial chiral amides using amylose tris[(S)-1-phenylethylcarbamate] (1997)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 9 (1997), S. 109-112 
    Details
    ISSN: 0899-0042
    Keywords: N-arylamides ; carbohydrate carbamate ; axial chirality ; Chemistry ; Organic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The enantiomeric resolution of a series of N-arylamides was examined on amylose tris[(S)-1-phenylethylcarbamate] coated onto aminopropylated 7 μm silica with 500 Å diameter pores and on naked silica 5 μm particle size with 500 Å diameter pores. The enantiomeric resolution obtained for this series was excellent on both columns. The enantioselectivity of cellulose and amylose tris (3,5-dimethylphenylcarbamate) coated onto APS-Hypersil (120 Å pore size, 5 μm particle size) was also investigated for this series of compounds.

    Preparative enantioseparation on polysaccharide phase using microporous silica as a support (1998)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 10 (1998), S. 573-577 
    Details
    ISSN: 0899-0042

    Topics: Chemistry and Pharmacology
    Notes: The preparative enantiomeric resolutions of hexahelicen-7-yl acetic acid methyl ester and two sulphoxides were performed on cellulose tris(3,5-dimethylphenylcarbamate) coated onto aminopropylated 5-μm silica with 120-Å diameter pore. High enantiomeric purity was obtained for both enantiomers. The enantioselectivity of the amylose tris(3,5-dimethylphenylcarbamate), cellulose and amylose tris(phenylcarbamate) phases for the hexahelicen-7-yl acetic acid derivative were also investigated.
