Abstract :
Bowl-shaped cyclic trimers of aromatic amides were simply synthesized in high yield by condensation reaction of meta-substituted 3-(alkylamino)benzoic acid using dichlorotriphenylphosphorane. The cyclic amides exist in syn conformation, which has a small chiral cavity, and a pair of each enantiomeric conformer formed a dimeric structure in the crystal.
