Abstract
Two chiral crown ethers (+)-(S)-(4) and (–)-(R,R)-(5) with a 4,4′-biphenanthryl moiety as the chiral centre have been prepared, and their chiral recognition properties were examined to show that (+)-(S)-(4) has a high enantiomer selectivity for 2-aminotetralin and 1,2-diphenylethylamine.Keywords
