Abstract
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.
