D. Velasco et al., CHROMATOGRAPHIC RESOLUTION OF SEVERAL RACEMIC 9-FLUORENYL DERIVATIVESON A BONDED CELLULOSE DERIVED CHIRAL STATIONARY-PHASE FOR HPLC, Tetrahedron : asymmetry, 7(3), 1996, pp. 633-636
The enantiomers of several 9-fluorenyl derivatives have been successfu
lly resolved by HPLC on a chiral stationary phase (CSP) based on a mix
ed 10-undecenoate/3,5-dimethylphenylcarbamate of cellulose bonded to a
llylsilica gel. Previous attempts at resolution, such as NMR methods,
GC and the use of a multiple interaction type chiral column for HPLC,
were unsuccessful. (C) 1996 Elsevier Science Ltd
