An intramolecularelectrocyclicreaction of 1,5-diphenylpenta-trans-1,trans-4-dien-3-one as the cation (generated with acetylium ions) affords, by conrotatory cyclisation, 2-acetoxy-trans-4,5-diphenylcyclopent-2-enyl sodium sulphate (XI), which is hydrolysed by hot 2N-sodium hydroxide or sodium carbonate solution with concomitant pinacolic change to 5-hydroxy-2,3-diphenylcyclopent-2-enone (X), sodium
