| Research Abstract |
(1) Redox-Photosensitization : In order to perform the photoamination of the substrates such as benzocycloalkenes, arylcyclopropanes, and quadricyclane that has no or weak absorption at near-ultraviolet regions, we applied the photosensitization using biphenyl derivatives and 2, 2-dialkoxy-1, 1'-naphthalene as the redox-photosensitizer. As the results, the photoamination of the substrates proceeded efficiently without the cosumption of the sensitizer.
(2) Photoamination in the presence of chiral π-donors : In order to attempt the asymmetric photoamination, the photoamination in the presence of chiral π-donors have been performed. When chiral benzyl menthyl ethers were used, the specific rotatory of the aminated products depended on the reaction temperature and the chiral π-donors used.
(3) Intercalation of chiral π-donors into β-cyclodextrins : Fluorescence spectral changes of (-)-and (+)-dialkyl 2-aryl-1, 3-dioxolane-4, 5-dicarboxylates having the methoxyphenyl group and the rigid conformation by the addition of b-cyclodextrin were investigated. In some cases, the enhancing effects on the fluorescence were different in (+)-and (-)-isomeres.
