## Abstract In the presence of chiral shift reagents the enantiotopic nuclei of a pair of enantiomers become diastereotopic and have the potential to give resolved NMR signals. Similarly, the enantiotopic nuclei within a __meso__ isomer become diastereotopic in the presence of a chiral shift reagen
