16-Hexahydroxytetraphenylene (5) was synthesized by an iodobenzene diacetate-mediated phenolic oxidation. Enantiopure forms of 1,4,5,8,9,16-hexahydroxytetraphenylenes [(S,R,S)-5 and (R,S,R)] were successfully synthesized either by using (S,S)-and (R,R)-1,8,9,16-tetramethoxytetraphenylenes [(S,S)-7 and (R,R)-7] as starting materials or by direct resolution of 1,4,5,8,9,16-hexahydroxytetraphenylene (5).
