A plausible biosynthetic pathway for the isomeric marine alkaloids papuamine and haliclonadiamine via the double tandem ene cyclisation of a tetraenediimine is proposed. Initial modelstudies directed toward the biomimetic synthesis of these alkaloids are described which illustrate that the Lewis acid-promoted ene cyclisation of methyl-2-(methoxycarbonyl)dodeca-2,8-dienoate is critically dependent
