The synthesis, separation, and solvolysis of the stereoisomeric dienynyltrifluoromethanesulphonates (1) are described, whereby the E-isomers, in contrast with the Z-isomers, rearrange to a remarkable extent to form the phenyl ethers (5)via the phenyl cations (2).

The selectivity in aromatic substitution vs conjugate addition during palladium catalyzed reactions has been controlled simply by changing the base. These reaction conditions have been applied to the syntheses of aromatized beta-ionone natural products 1 and its dihydro-derivatives 7. (C) 1998 Elsevier Science Ltd. All rights reserved.
