Notizen:
Enantioselective HPLC methods have been developed for the resolution of (RS)-2-phenylcyclohexanone (compound 1) and (RS)-2-phenyltetrahydropyran-4-one (compound 4) and the diastereoselective and enantioselective separations of their respective cis- and trans-alcohols; reduction of compound 1 yields trans- and cis-2-phenyl-1-cyclohexanol (compounds 2 and 3, respectively) and reduction of compound 4 yields trans- and cis-2-phenyl-tetrahydropyran-4-ol (compounds 5 and 6, respectively). Compounds 1, 2, and 3 were stereochemically resolved using a chiral stationary phase (CSP) based upon amylose tris(3,5-dimethylphenyl carbamate) coated on 10 μm silica-gel (Chiralpak AD-CSP). Compounds 4, 5, and 6 were stereochemically resolved on a coupled column system where a column containing a CSP based upon cellulose tris(3,5-dimethylphenyl carbamate) coated on 5 μm silica (Chiralcel OD-H-CSP) was coupled in series to the AD-CSP. The strategy employed in the identification of the peaks in the respective chromatograms is also discussed in this presentation. Chirality 8:551-555, 1996. © 1997 Wiley-Liss, Inc.
