Use of shift reagent with MTPA derivatives in19F NMR spectrocopy: IV—Determination of enantiomeric composition for a variety of secondary cycloalkanols. A survey
摘要:
AbstractChiral secondary cycloalkanols (monocyclic alcohols) are derivatized to the corresponding (R)‐α‐methoxy‐α‐trifluoromethyl‐α‐phenylacetic acid [(R)‐MTPA] 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) [Eu(fod)3]. Using this method the enantiomeric composition can be measured for several 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.
