Giguere, Raymond J. published the artcileIntramolecular [3 + 4] allyl cation cycloaddition: novel route to hydroazulenes, Recommanded Product: Allyldiphenylphosphine oxide, the publication is Tetrahedron Letters (1988), 29(47), 6071-4, database is CAplus.
Intramol. Hoffmann-Noyori reaction of acyclic trienol I permits direct entry to hydroazulenes II with modest diastereoselectivity. Cycloaddition precursor I is readily prepared from 1,5-pentanediol in seven steps.
