Microwave dielectric heating proved to be an efficient method for the one-pot and stepwise syntheses of symmetrical and unsymmetrical naphthalenediimide derivatives of α-amino acids. Acid-labile side chain protecting groups are stable under the reaction conditions; protection of the α-carboxylic group is not required. The stepwise condensation of different amino acids resulted in high yields of unsymmetrical

We report a dynamiccombinatoriallibrary that, upon binding of an electronically-complementary guest, produces in high yield a tetrameric receptor with flat hydrophobic, electron-deficient surfaces and flexible, water-soluble disulfide-containing linkers; analysis of the dependence of library composition on template concentration gives insight into the binding behaviours of the species involved.
