title: A chiral A2 B2 macrocyclic minireceptor with extreme enantioselectivity.
abstract: We describe a novel macrocyclic minireceptor that is assembled from a chiral 1,2-diamine and 5-allyloxyisophthalic acid. After immobilization on HPLC silica, the chiral macrocycle preferentially binds the L-enantiomers of simple amino acid derivatives, with enantioselectivities values up to 3.0 kcal/mol.
