, p. 7475 - 7478 (2007/10/02)
Reaction of triarylbismuth difluorides 1 with allyltrimethylsilane 2 in CH2Cl2 in the presence of BF3·OEt2 at low temperature generates allyltriarylbismuthonium compound 3 as a pale yellow solution, in which aromatic hydrocarbons and ethers, triphenylphosphine, dimethyl sulfide, p-toluenesulfinate, and thiophenol are all readily allylated to afford the corresponding allyl derivatives in moderate to good yields.
Total synthesis of 2-tetraprenylbenzoquinol and -benzoquinone

, p. 714 - 718 (2007/10/02)
The total synthesis of 2-tetraprenylbenzoquinol and -benzoquinone is described. A key step in this synthesis is the highly regio- and stereoselective coupling between an appropriate aromatic allylcarbonate and an activated bifunctional farnesyl derivative

Prenyl and geranyl diisopropyl phosphates readily alkenylate a variety of phenolic ethers regio- and stereospecifically without any appreciable side reactions.
Acid-catalysed Intramolecular Cyclization of Geranyl Hydroquinone Derivatives from Cordia alliodora. X-Ray Crystal and Molecular Structure of 1,2,3,3a,4,9,10,10a-Octahydro-5,8-dimethoxy-3,10-dimethyl-3a,9-epoxybenzazulene

The aqueous acid-catalysed intramolecular cyclization of dimethylated alliodorin (2) obtained from the heartwood of Cordia alliodora has been characterized by X-ray analysis as the unusual tetracyclic di-O-methyl hydroquinone title compound (8).A new synthesis of di-O-methylalliodorin (2) from a terminal methylallylic sulphide derivative of 2-geranil-1,4-dimethoxybenzene is described. Crystals of the title compound (8) are monoclinic, space group P21/c, unit cell dimensions a = 14.984(7), b = 5.206(4), c = 20.131(9) Angstroem, β = 99.77(1) deg, Z = 4.The structure was solved by direct methods and refined by least-squares calculations to an R value of 0.078 for 1 832 independent reflections measured on a diffractometer using Cu-Kα radiation.
