Various poly-substituted benzenes including terphenyl, quaterphenyl, and quinquephenyl were synthesized starting from the Morita–Baylis–Hillman bromides. The synthesis was carried out via a three-step protocol, namely, a sequential Wittig reaction, Diels–Alder reaction with DMAD, and an aerobic oxidation.
