Intramolecular Photochemistry in β-Turned Dipeptide Bridged Molecules

Article abstract of DOI:10.1246/bcsj.66.1768

Several benzophenone-β-turned dipeptide-alkyl chain molecules were prepared.In acetonitrile, intramolecular photochemical reaction of the synthetic molecules was investigated.The photoexcited benzophenone moiety abstracted selectively a hydrogen of the alkyl chain in the molecule.Such a site selectivity showed that the β-turned conformation might be rigid enough for the hydrogen abstraction in the excited state.
