title: Synthesis and Diels-Alder reactions of 1,2-dimethylene[2.n]metacyclophanes.
abstract: The Diels-Alder reaction of 1,2-dimethylene[2.n]MCPs (MCP = metacyclophane) with suitable dienophiles followed by aromatization and photoinduced or FeCl(3)-induced transannular cyclization afforded phenanthrene-anellated polycyclic aromatic hydrocarbons, which were found to adopt helical chirality in the solid state.
