Synthesis of 1,8,13-substituted triptycenes

Abstract

Triptycene is an aromatic compound with D3h symmetry, where three benzene rings are fused to a bicyclo[2.2.2]octatriene skeleton. 1, 8, 13-Substituted triptycenes exhibit interesting structural features: the C-1, 8, 13 substituents and the bridgehead C-9 position are located in the same plane. Three faces of the molecule are open for interesting interactions and applications. This paper summarizes the syntheses of 1, 8, 13-substituted triptycenes.
