Remarkable effects of chirality on deslipping reactions of diastereomeric rotaxanes and relevant mechanism involving pre-equilibrium

The first clear differentiation on deslipping rates affected by the difference in the diastereomeric stereocenters of rotaxanes up to 8.4 times and unexpectedly large steric kinetic isotope effect on the deslipping reaction.

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.

Chiral recognition of secondary amines by using chiral crown ether and podand

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-α-dimethylbenzylamine (15) and propranolol (16).
