Cyclic triamides 4 bearing amidino groups at the meta position of the phenyl rings were synthesized, and their conformational properties in the crystal and in solution were examined. Compound 4a exists as a capsule‐type dimer of the enantiomers with a bowl‐shaped syn conformation in the crystal state. Compound 4 exists mainly in the syn form in solution, and chiral induction was observed upon addition of a chiral acid to a solution of 4a .
