Total Syntheses of the meta,meta-Bridged Biphenyls (+/-)-Myricanol and Myricanone, and of an Isomeric Biphenyl Ether, a 14-Oxametaparacyclophane

The oxidative coupling of 1,7-bis(hydroxyphenyl)heptanoids (2a,b) has been investigated: C-C coupling to meta,meta-bridged biaryls was not observed, but with thallium tris(trifluoroacetate) C-O coupling occurred forming a 14-oxametaparacyclophane analogous to the natural phenols acerogenin-A and galeon.Intramolecular reductive coupling, using tetrakis(triphenylphosphine)nickel(0), of the bis-iodides (11a,b) derived from phenols (2a,b), leads, after deprotection, to the desired meta,meta-bridged biphenyls myricanone and (+/-)-myricanol, albeit in rather low yield.OO-Dimethylmyricanone and (+/-)-OO-dimethylmyricanol were similarly synthesized.Irradiation (254 nm) in alkaline ethanol of the bromides (11g,h) also induced aryl-aryl coupling to form dibenzylmyricanone and (+/-)-dibenzylmyricanol acetate respectively.
