title: First total synthesis of JS isoprostane.
abstract: A stereoselective Julia-Lythgoe olefination followed by an efficient 1,3-allylic transposition of the C-9 hydroxyl group of compound 13 has allowed the first total synthesis of J(2) isoprostane (1), a recently discovered member of the growing isoprostane family. This elusive compound opens up numerous new avenues for the molecular biology of cyclopentenone prostaglandins which are endowed of intriguing biological effects such as antitumor, antiinflammatory, and antiviral activities. In principle, our approach is flexible enough to allow an easy synthesis of other isoprostanes of the J family following the same methodology.
