Contractive Annulation: A Strategy for the Synthesis of Small,Strained Cyclophanes and Its Application in the Synthesis of [2](6,1)Naphthaleno[1]paracyclophane
A new synthetic strategy (contractive annulation) for the synthesis of highly strained cyclophanes has been conceived and its viability has been demonstrated through a nine‐step synthesis of 2](6,1)naphthaleno1]paracyclophane from 2.2]paracyclophane.
