Abstract

(Chemical Equation Presentation) Intriguing scaffolds: Tetraphenylenes with symmetry-breaking substitution have chiral π systems and extraordinarily high barriers for racemization. Their applications as building blocks for chiral materials and as ligands in asymmetric syn-thesis are hindered by the difficulty in obtaining the chiral tetraphenylene core. Rhodium-catalyzed [2+2+2] cycloadditions of triynes provide an effective alternative synthesis.
