The stereoselectivity of the photochemicalring-opening of 6-acetoxy-6-methylcyclohexa-2,4-dienones to derivatives of hepta-3,5-dienoic acid has been shown to be general, and the stereochemistry of the products has been studied by use of n.m.r. long-range coupling and solvent-shift data. Two representative 6-benzoyloxy-analogues behave in a similar manner.
