While enantiotopic hydrogens of a methylene group are isochronous in an achiral environment, this is no longer true in a chiral one. In an unrelated study of the diastereomers derived from the R and S enantiomers of 2- and 3-hexanol, we prepared the 1-(R)-10-camphorsulfonate ester of 1-hexanol. While all of the methylene hydrogens of 2- and 3-hexanol are diastereotopic due to the nearby asymmetric center, the methylene hydrogens at C-1 of 1-hexanol are enantiotopic; however, in the sulfonate ester they are diastereotopic and hence anisochronous with appreciably different chemical shifts. This signal shows 10 distinct lines. A simpler example of this phenomenon is provided by the ethyl ester of 1-(R)-10-camphorsulfonic acid (CSA). Instead of the usual quartet these protons now show 12 lines. This seems to be a useful pedagogic example to present to our students. Because of the difference in chemical shifts of the methylene hydrogens we can measure both the vicinal and the geminal coupling constants.
