Preparation and Enantiomer Recognition of Chiral Azophenolic Crown Ethers Having three Chiral Barriers on each of the Homotopic Faces

Article abstract of DOI:10.1016/0957-4166(95)00240-P

Homochiral azophenolic crown ethers 1 and 2 having three chiral barriers, that is, the phenyl group, the methyl group, and the cyclohexane moiety on each of the homotropic faces have been prepared.The enantiomer recognition toward chiral 2-aminoethanol derivatives has been examined.
