WebEnantiotopic Protons: Enantiotopic protons normally have identical chemical shifts. However, when the molecule is placed in a chiral environment (say with an optically active solvent, cosolvent or Lewis acid) then the protons can become diastereotopic. This is in contrast to homotopic protons, which are always identical. Diastereotopic Protons: WebMay 12, 2024 · Enantiotopic protons have the same chemical shift in the vast majority of situations. However, if they are placed in a chiral environment (e.g. a chiral solvent) they will have different chemical shifts. The second sentence in this question piques my interest. Even after some searching, I only saw this same sentence over and over again.
