Synthesis and optical resolution of inherently chiral difunctionalized tribenzotriquinacenes

The preparation of inherently chiral tribenzotriquinacenes (TBTQs) bearing one single mono- or difunctionalized aromatic aromatic nucleus and the optical resolution of one of the derivatives, TBTQ-based salicy lic acid, are described. Efficient access to enantiopure, inherently chiral tribenzotriquinacenes has helped in the studies of novel container compounds, supramolecular aggregation, chiral recognition and asymmetric catalysis.
