Outline of Final Research Achievements |
Syntheses of planar planar-chiral cyclophane derivatives and their stereochemical property was studied by exploiting the orthogonal Suzuki-Miyaura coupling strategy by using a selectively-protected phenyldiboronic acid derivative and planar-chral carba-paracyclophane units. This method enabled efficient assembly of various heptaphenylene derivatives incorporating non-substituted phenylene spacers. circular dichroism (CD) spectra of these oligophenylenes show characteristic CD curve patterns, suggesting a helical conformation on their oligophenylene axis.
