Chirality transcription and amplification by [2]pseudorotaxanes

Chem Commun (Camb). 2013 Mar 18;49(22):2186-8. doi: 10.1039/c2cc38758a.

Abstract

Chirality transcription and amplification by the formation of chiral [2]pseudorotaxanes by an achiral crown ether having the 2',2''-quaterphenyl group and chiral sec-ammonium ions are reported. It was revealed that the absolute configurations of the chiral sec-ammonium ions can be detected directly from the CD spectra of the chiral [2]pseudorotaxanes.
