Abstract

The invention relates to processes for the chromatographic separation of enantiomeric esters from 2-alkanoyl-chromane derivatives of the formula (I) in which Z is -(CH2)n1-(CHA)n2-(CH2)n3, where n1 = 0, 1, 2 or 3, n2 = 0 or 1, n3 = 0, 1, 2 or 3, with the proviso that n1 + n2 + n3 < 4, R<6>, R<7>, R<8> and R<9> are mutually independently H, A, OA, phenoxy, OH, F, Cl, Br, I, CN, CF3, NO2, NH2, NHA, NA2, Ac, Ph, cycloalkyl with 3 to 7 atoms, -CH2NH2, -CH2NHA, -CH2NA2, -CH2NHAc or -CH2NHSO2CH3, where two neighbouring radicals may also be an alkylene chain with 3 or 4 C atoms, A is alkyl with 1 to 6 C atoms, Ac is alkanoyl with 1 to 10 C atoms or aroyl with 7 to 11 C atoms, Ph is unsubstituted or R<5>, 2, 3 or 4-pyridyl or phenoxy-substituted phenyl, R<5> is unsubstituted or 1-5 F, CF3 or wholly or partially fluorine-substituted A, A and/or OA-substituted phenyl, by means of chromatography on sorbents containing aromatic carbamate-substituted polysaccharides, e.g. cellulose, especially cellulose-tris(3,5 dimethyl phenyl carbamate), using eluents containing C1 to C5 alcohols. Suitable eluents are C1 to C5 alcohols, especially methanol and ethanol or their mixtures. Preferred eluents are C1 to C5 alcohols and C1 to C10 hydrocarbons, especially mixtures of hexane or heptane with 2-propanol.
