The synthesis of a family of farnesol analogues, incorporating aromatic rings, has been achieved in high yields through the development of a regioselective coupling of allylic tetrahydropyranyl ethers with organometallic reagents. The allylic THP group is displaced readily by Grignardreagents in the presence of Cu(I) halides but is stable in the absence of added copper. Thus, an allylic THP group
