The first example of metal Lewis acid-primary amine bifunctional cooperative catalyst derived from primary amino acids was developed, and it was found to catalyze aldolreactions of cyclic ketones highly efficiently with very good to excellent stereoselectivities.

A novel macrobicycle featuring an amidopyridine unit as a carboxylic acid binding site, and amide functionality to provide further hydrogen bonding interactions with suitable guests has been prepared. The ability of this novel macrobicycle to bind peptide derivatives has been investigated.
