## Abstract The magnetic nonequivalence of the __O__‐methylene protons of certain __N__‐trityl amino acid benzyl esters is reported. It is shown that magnetic asymmetry arises from hindered internal rotation of the α‐benzyl group. The degree of proximity of the bulky __N__‐trityl to the α‐benzyl gr
