    Notes: Some 3-t-butyldimethylsilyloxy derivatives, synthesized from the cheap commercially available (1S,2S)-2-amino-1-phenyl-1,3-propanediol [(1S,2S)-1], have been successfully employed as new chiral ligands in the asymmetric Reformatsky reaction on aldehydic substrates. The influence both of the substrate and of the ligand on the stereochemical pathway has been investigated by varying the structure of the carbonyl substrate and of the optically active aminodiols. © 1995 Wiley-Liss, Inc.

    Circular dichroism detection in HPLC (1991)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 3 (1991), S. 376-385 
    Details
    ISSN: 0899-0042
    Keywords: circular dichroism ; detection system ; chromatography ; chiral discrimination ; enantiomeric excess ; elution order ; dissymmetry factor ; Chemistry ; Organic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A circular dichroism-based detection system presents several advantages in the HPLC analysis of chiral compounds because of the selective monitoring of optically active molecules. Its use allows reliable determination of enantiomeric excesses and elution order. To this end, the application of empirical, semiempirical, and nonempirical methods to get stereochemical information from the CD signal is reported. Furthermore, recording the CD spectra on line and evaluation of the dissymetry factor make the CD detection very powerful in characterizing the stereochemistry of chiral eluates.
