The structures of dimethyl 8,8-dimethoxy-7-oxo-1,4-(1, 1-dimethoxy-2-oxoethano)-1,4,4a,7,8,8a-hexahydronaphthalene-2,4a-diyldiacrylate, C24H28O10, (I), and its photocage product, dimethyl 6,6,12,12-tetramethoxy-5,11-dioxotetracyclo[6.2.2.03,10.0 4,9]dodecane-2,9-diyldiacrylate, C24H28O10, (II), were determined in order to investigate the conformational change caused by the intramolecular [2+2] photoreaction. The high efficiency (70%) of the photoreaction of (I) in a 1,4-dioxane solution is attributed to the fact that two C=C double bonds in (I) can become close and parallel to each other simply by changing the configuration of the cyclohexene ring moiety from an envelope to a sofa form. Compound (I) is much less photoreactive in the solid state than in solution.
