Abstract
A calix[3]aramide has been synthesized bearing three triphenylphosphinic amide moieties, which formed intramolecular cyclic hydrogen bonds that suppressed its <i>cone</i>/<i>partial cone</i> inversion. The intramolecular cyclic hydrogen bonds were disrupted by DMSO, and the insertion of H<sub>2</sub>O into the hydrogen bonds triggered the spontaneous resolution of the calix[3]aramide. Within a chiral environment, such as that afforded by the presence of optically active 2-butanol, the calix[3]aramide underwent a symmetry breaking crystallization process- Dataset
