Synthesis of [2]Catenanes by Intramolecular Sonogashira-Type Reaction

Synthesis of [2]Catenanes by Intramolecular Sonogashira-Type Reaction
Shinichi Saito, Yuichiro Mutoh, Ken Ito
The catalytic activity of macrocyclic phenanthroline-CuI complexes was utilized to synthesize [2]catenanes by intramolecular Sonogashira-type reaction. The high reactivity of the acyclic starting material was critical to synthesize the [2]catenane in acceptable yields. The relationship between the yield of the [2]catenane and the structure of the starting materials was disclosed.
