Preparation of phenolic chiral crown ethers and podands and their enantiomer recognition ability toward secondary amines

Phenolic pseudo-24-crown-8 (S,S)-3, pseudo-27-crown-9 (S,S)-4, and podands (R,R)-5 and (R,R)-6 possessing phenyl groups as chiral barriers were prepared and their chiral recognition properties toward secondary neutral amines were examined. Pseudo-24-crown-8 (S,S)-3 and podand (R,R)-5 showed sufficient binding ability and moderate chiral recognition ability toward secondary amines.
