For the cis-O,O,N-tris-?-homobenzenes 1a,b three alternative syntheses, ultimately starting from benzene or p-quinone, have been devised.In the course of one of these approaches the radical bromination of (tosylimino)-1,4-cyclohexadiene and the equilibrat

cis-Dioxa,aza-tris-(8) and cis-oxa, aza-bis-σ-homobenzenes (21) have been synthesised. With activation barriers, which clearly support the concerted mechanism, they undergo [2+2+2]-cycloreversion yielding 7H-1,4,7-dioxazonines (9) and 4H-1,4-oxazocines (22), resp.
