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

    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.

    Enantiomeric resolution of chiral sulfoxides on polysaccharide phases by HPLC (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 8 (1996), S. 147-152

    ISSN: 0899-0042
    Keywords: amylose ; (S)-α-methylbenzyl carbamate ; chiral sulfoxides ; microporous silica ; polysaccharide phases ; Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: The enantiomeric resolution of chiral sulfoxides was investigated on amylose (S)-α-methylbenzyl carbamate phase coated on aminopropylated 7 μm silica with 500Å diameter pores. This was shown to be very successful in the separation of alkyl/aryl, aryl/aryl, and non-aromatic sulfoxides. The effect of pore size using naked silica was also investigated, demonstrating that the pore size does not affect the resolution. © 1996 Wiley-Liss, Inc.

    Carbohydrate carbamate coated onto microporous silica: Application to chiral analysis of commercial pharmaceutical drugs (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 8 (1996), S. 143-146

    ISSN: 0899-0042
    Keywords: Cellulose tris-(3,5-dimethylphenyl carbamate) ; resolution ; tetramisole ; propanolol ; microporous APS-silica ; Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: The enantioselectivity of a series of chiral analytes was examined on tris-(3,5-dimethylphenyl carbamate) coated onto microporous APS-silica. The effects of the nature of the carbohydrate, the weight ratio of carbamate/support and the type of alcohol present in the mobile phase were investigated. Among the chiral analytes examined, propanolol showed an extremely good resolution. The resolution of tetramisole was optimized and the method developed was shown to be suitable for analysis of the drug in commercial tablets and in a suspension. © 1996 Wiley-Liss, Inc.
