Photocycloaddition reactions of 5,5-dimethyl-3-(3-methylbut-3-en-1-ynyl) cyclohex-2-en-1-one

The title cyclohexenone 1d undergoes photodimerization selectively at the exocyclic C=C bond to give a 1 :1 mixture of 1,2-dialkynyl-1,2- dimethylcyclobutanes 6 and 7. On irradiation in the presence of 2,3-dimethylbuta-1,3-diene, 1d affords bicyclo[8.4.0]tetradeca-1,2,3,7-tetraen- 11-one 9. This - formal - (6+4)-cycloadduct undergoes quantitative isomerization to 3-cycloheptadienyl-2,5,5-trimethylcyclohex-2-enone 11 on treatment with basic silica gel.
