    HPLC with carbohydrate carbamate chiral phases: Influence of chiral phase structure on enantioselectivity (1994)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 6 (1994), S. 135-140

    Notes: The enantioselective resolution of trans-stilbene oxide and of 23 chiral sulfoxides was investigated on cellulose and amylose tris(arylcarbamate) stationary phases coated on aminopropylated 7 μm spherical silica with 500 Å diameter pores. Cellulose tris-(3,5 dimethylphenylcarbamate) showed good resolving power for many of the sulfoxides and amylose tris-(3,5 dimethoxyphenylcarbamate) showed advantages for the resolution of certain sulfoxides which were not separated on other phases. © 1994 Wiley-Liss, Inc.

    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

    ISSN: 0899-0042
    Keywords: hexahelicene ; sulphoxides ; carbohydrate carbamate ; chiral preparative ; silica ; Chemistry ; Organic Chemistry

    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.
