Outline of Final Research Achievements |
In this study, we established precise synthesis and helical chirality induction of ortho-linked oligo(naphthalene-2,3-diyl)s. Oligo(naphthalene-2,3-diyl)s with a terminal boronyl group were synthesized by iterative Suzuki-Miyaura cross-coupling of 3-iodo-2-naphthylboronic acid bearing 1,8-diaminonaphthalene as a protecting group on the boron atom. Hydrolysis of the protecting group and subsequent condensation with chiral diols gave helically chiral oligo(naphthalene-2,3-diyl)s. Furthermore, using 2-pyrazolylaniline as a removable directing group on the boron atom, we developed an efficient synthetic method for 1,2-diboryl arenes via iridium-catalyzed aromatic ortho-C-H borylation of arylboronic acids.
