One-pot synthesis of azabora[6]helicene by a Schiff base forming reaction

Chem Commun (Camb). 2024 Mar 26;60(26):3543-3546. doi: 10.1039/d4cc00168k.

Abstract

Azabora[6]helicene as a new heterohelicene analogue was synthesized by a one-pot reaction of commercially available 2,6-diaminopyridine and benzo[c,d]indole-2(1H)-one and subsequent boron coordination. While the single-crystal X-ray diffraction analysis elucidated a helical structure in the solid state, a dynamic helicity inversion was observed in solution.
