A series of benzoyl leucine amides of varying electronic character were prepared. All of the 3‐ and 3,5‐disubstituted compounds assembled into homochiral dimers in the solid state. However, no homochiral dimerization was observed in the unsubstituted case and in several 4‐substituted cases (shown in yellow). The crystallographic data suggests that local interactions between the dipoles may stabilize the interaction in several of the dimers (shown in red) and provides a driving force for homochiral dimerization.
