We have taken advantage of the ability of the cyclic triester of l-serine to organize ligand units appended to the three α-amine functionalities, as in enterobactin, a siderophore produced by enteric bacteria that binds ferric ion exceptionally well (Kf = 1049). As an extension of the preorganization concept, this work describes the preparation and characterization of carbamate triserine lactone receptors 1-6 and their ability to act as molecular receptors for anions. These receptors bind halides (F- ? Cl- > Br- > I-) with binding constants K in the range 21-7350 L mol-1.
