| Outline of Final Research Achievements |
Synthesis of catenanes was carried out by olefin metathesis, oxidative homo-coupling reaction of terminal alkynes, and Husigen reaction between alkyne with azide. Reaction conditions to introduce fluorous tags into nitrogen atoms of catenanes was investigated. Thus, trifluoromethanesulfonyl- and pentafluorobenzenesulfonyl-groups were introduced to catenanes to obtain the corresponding fluorous-tagged catenanes in good yields. Due to the steric hindrance of sulfonyl groups, rotation of the rings of the catenanes was blocked to give topological isomers.
