L. Siret et al., SEPARATION OF THE OPTICAL ISOMERS OF A NEW 1,4-DIHYDROPYRIDINE CALCIUM-CHANNEL BLOCKER (LF 2.0254) BY LIQUID AND SUPERCRITICAL-FLUID CHROMATOGRAPHY, Chirality, 6(5), 1994, pp. 440-445
The four optical isomers of a new calcium channel blocker LF 2.0254 (d
eveloped by Laboratoires Fournier) are resolved by chromatography usin
g chiral stationary phases. Two methods are proposed: the first one in
volving two chiral stationary phases [(S)-N-(2-naphthyl)alanine, a Pir
kle type CSP and Chiralcel OJ, a cellulose derived CSP] in the liquid
chromatographic mode, the second one involving a single CSP (Chiralcel
OJ) in the supercritical fluid chromatographic mode. (C) 1994 Wiley-L
