Synthesis and Dimerization Properties of Cup‐ and Bowl‐shaped Cyclic Trilactams

The long-awaited synthesis and self-assembly of a small rigid C3-symmetric trilactam

The challenging synthesis of a fused C₃-symmetric trilactam (1) was executed in racemic and enantiomerically pure form. The rigidity, symmetry and high density of hydrogen bonding motifs make 1 an attractive candidate for self-assembly study, which revealed different hydrogen bond patterns in the crystals of rac-1-d₃ and (+)-(SSS)-1.

Application of cup-shaped trilactams for selective extraction of volatile compounds by gas chromatography-mass spectrometry

Chiral cup-shaped trilactams were used as liquid phase extraction material of volatile organic compounds in perfume analyzed by SPME GC-MS. (+)-material showed higher selective chiral recognition with oxygenated and cyclic volatile compounds.
