Palladium-catalyzed cross-coupling of 2-iodobiphenyls with ortho-chloroacetophenones through dual C–H arylation for the construction of tribenzo[a,c,f]cyclooctanones

“…Furthermore, elegant approaches have been developed for the synthesis of dibenzocyclo-octaphenanthrenes through electrocyclic reactions and subsequent dimerization of dienediynes (Fig. 1, c) 8 or tandem single-electron oxidative ring expansion reaction of seven-membered substrates (Fig. 1, d).…”
