Syntheses of chiral calixarene analog incorporating amino acid residues: Molecular recognition for a racemic ammonium ion by the macrocycles

Article abstract of DOI:10.1246/cl.1998.1221

Chiral calixarene analog incorporating amino acid residues into macrocyclic rings was prepared. The macrocycles form a chiral concave, which is induced by the chiral transmission from the amino acid to the phenol-formaldehyde tetramer unit through the hyd
