Abstract Diversely functionalized, fused aryl–alkyl ring systems hold a prominent position as well-established molecular frameworks for a variety of anti-cancer agents. The benzosuberene (6, 7 fused, also referred to as dihydro-5H-benzo [7] annulene and benzocycloheptene) ring system has emerged as a valuable molecular core component for the development of inhibitors of tubulin assembly, which function as antiproliferative anti- ...
