Systems in which an external stimulus elicits a response through some sort of modification at the molecular or supramolecular level bear potential for the development of smart materials and devices. This work describes a versatile synthetic approach suitable for the stepwise incorporation of multiple, even consecutive, units of the simplest Cα,β-unsaturated β-amino acid, (E/Z)-3-aminoprop-2-enoic acid, in peptide-based foldamers. The properties of these, including photoinduced E/Z isomerizations, were investigated.

For a novel family of oxanorbornene β-peptides, density functional theory computations of the three-dimensional structure and 1H NMR chemical shifts predict that the dimer and trimer form consecutive 8-membered hydrogen-bonded ring helices, which is supported by excellent agreement with experimental solution NMR data.
SYNTHESE DE β-AMINOACIDES PONTES ET LEUR THERMOLYSE EN DEHYDRO β-AMINOACIDE ET EN OXAURACILE

Reactions of bridged dicarboxylic anhydride derivatives with sodium azide in THF give the corresponding, N-tert-butyloxycarbonyl β-aminoesters 2(a-c), which can be cyclized to oxanorborno- and norbornouracils 6(a-c).Pyrolysis of these adducts leads to dehydro-β-alanine 5 and oxauracil 7.
