Photo-induced addition reaction of norbornene and dimethyl maleate afforded exo-3,4-dicarbomethoxy-cis, rans, cis-tricyclo[4,2,1,02,5]nonane (I) exclusively. In a similar way, the photochemical reaction of dimethyl acetylene dicarboxylate and norbornene gave rise to the 1:1 photo-adduct having the similar configuration, exo-3,4-dicarbomethoxy-tricyclo[4,2,1,02,5]nona-3-ene. Moreover, it was confirmed
降冰片烯的光诱导加成反应和马来酸二甲酯,得到外切-3,4- dicarbomethoxy-顺,失败者,顺式-三环[4,2,1,0 2,5 ]壬烷(I)只。类似地,乙炔二甲酸二甲酯和降冰片烯的光化学反应产生了具有相似构型的1:1光加合物,exo -3,4-二苯甲氧基三环[4,2,1,0 2,5 ]壬基-3-烯。此外,证实了上述反应没有通过电荷转移络合物进行。
