Brown, Herbert C. published the artcileB-2′-Isoprenyldiisopinocampheylborane: an efficient reagent for the chiral isoprenylation of aldehydes. A convenient route to both enantiomers of ipsenol and ipsdienol, Related Products of ethers-buliding-blocks, the publication is Tetrahedron Letters (1990), 31(4), 455-8, database is CAplus.
B-2′-Isoprenyldiisopinocampheylborane is prepared by metalation of isoprene with potassium 2,2,5,5-tetramethylpiperidide followed by sequential treatment with B-methoxydiisopinocampheylborane and boron trifluoride-etherate. Condensation of this reagent with aldehydes provides isoprenylated chiral alcs. This methodol. is utilized for an efficient one-pot synthesis of both enantiomers of the pheromones of the bark beetle Ips paraconfusus Lanier, ipsenol (I) and ipsdienol (II) in 96% ee and 65% isolated yield.
