Chiral secondary cycloalkanols (monpocyclic alcohols) are derivatized to the corresponding (R)-α-methoxy-α-trifluoromethyl-α-phenylacetic acid esters and analysed by 19F NMR in the presence of tris(6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato)europium(III) .Using this method the enantiomeric composition can be measured for severak cyclopentanols, cyclohexanols and cycloheptanols, with a variety of substitution patterns.It is shown that a mixture of four stereoisomeric cycloalkanols, such as cis and trans disubstituted alcohols, can be analysed simultaneously.
