| Outline of Final Research Achievements |
Introduction of axial and helical chirality to carbazoles (CBZ), which have remarkable electro and photo properties, may lead to characteristic chiral functional materials. To this end, we have developed catalytic asymmetric hydroarylation of linked alkyne-indole systems and thereby, achieved the synthesis of CBZ-biaryl derivatives with axial chirality in high optical purity. Furthermore, transformation of the CBZ bialys thus obtained to heterohelicenes was examined to permit successful asymmetric synthesis of CBZ-helicenes with both helical and axial chirality.
