Zusammenfassung:
The synthesis of a shape-persistent macrocycle with two intraannular sulfonate groups is described. The cylization step is the oxidative acetylene coupling of large phenylethynyl oligomers which are covalently connected to a template. The synthesis of the templated acetylenes at the template as well as the cyclization step give high product yields showing that the template-directed approach is superior to statistical oligocyclizations.
