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.
报告了通过具有 2′,2′′-四联苯基团的非手性冠醚和手性仲铵离子形成手性[2]假杉烷的手性转录和放大。研究表明,手性仲铵离子的绝对构型可以直接从手性[2]伪对二甲苯的 CD 光谱中检测到。
