โœฆ Synopsis

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.

Chiral crown ether (S,S)-3 having a pseudo-24-crown-8 ring and chiral podand (R,R)-4 were prepared and both exhibited good chiral recognition ability toward secondary amines, N-a-dimethylbenzylamine (15) and propranolol ( 16).
