Lateral Extension of π Conjugation along the Bay Regions of Bisanthene through a Diels-Alder Cycloaddition Reaction

Diels–Alder cycloaddition reactions at the bay regions of bisanthene (1) with dienophiles such as 1,4‐naphthoquinone have been investigated. The products were submitted to nucleophilic addition followed by reductive aromatization reactions to afford the laterally extended bisanthene derivatives 2 an...
