A Facile Synthesis of Large Extraannular-Functionalized Phenyl-Ethynyl Macrocycles Containing m-Terphenyl Units

Abstract
[reaction: see text] Two large extraannular-functionalized phenyl-ethynyl macrocycles containing m-terphenyl units are described. The synthesis of the m-terphenyl building blocks is based on the transformation of pyrylium salts to arenes.
