Substituted cyclohexenone fragment

The acid fragmentation of suitably substituted bicyclo[2.2.2]octanes to cyclohexenones and subsequent ring closure to spirovetivanes via ir-cation cyclization has been used by Murai for a highly stereoselective isolubimin (56) synthesis. (56) has been considered to play an important role in the bio-genetic pathway of various spirovetivane phytoalexins in the Solanaceae family. Treatment of methyl... [Pg.1049]
