Synthesis and Chiral Recognition of Optically Active Crown Ethers Incorporating a 9,9′-Biphenanthryl Moiety as the Chiral Center

Abstract
Two chiral crown ethers incorporating a 9,9′-biphenanthryl moiety as the chiral center have been prepared, and their chiral recognition properties in transport of methyl (±)-phenylglycinate hydrochloride, (±)-1-phenylethylamine hydrochloride, and (±)-1,2-diphenylethylamine hydrochloride were examined.
