中文摘要：

合成了两个N-（ω-三甲基硅烷基醚）马来酰亚胺衍生物（Za，2b），并以2a，2b为光反应底物在HCN，MeOH，30％H2O-HCN，丙酮等溶剂中进行了光反应．结果显示，化合物2a在强的亲硅性溶剂MeOH，30％H2O-MeOH，30％H2O-HCN中经单电子转移反应以很高的产率和区域选择性生成环胺醇产物3，在HCN、丙酮等弱的亲硅性溶剂中发生[2＋2]环加成副反应生成双分子偶合产物5；2b无论是在强的亲硅性溶剂，还是在弱的亲硅性溶剂HCN、丙酮中，都发生分子内单电子转移反应，生成分子内双离子自由基中间体8．一部分8发生脱三甲基硅烷基反应生成环化物4的前体分子内双自由基9，多数8发生特殊的分子间偶合反应得到不对称双分子偶合产物6．所有新化合物均经NMR和质谱验证．

英文摘要：

Two N-（ω-trimethylsilylether）maleimides （2a, 2b） were synthesized and their photoreaction procedures in different solvents, such as HCN, MeOH, 30% H2O-MeOH, 30% H2O-HCN and acetone, were investigated respectively. The results showed that, 2a occurred intramolecular single electron transfer （SET） to provide cyclic amidol 3 with highly yield and highly regioselectivity in silophiles such as MeOH, 30% H2O-MeOH, 30% H2O-MeCN, and occurred side reaction to produce [2＋2] dimerization product 5 in the weak silophiles HCN and acetone. 2b occurred intramolecular SET to provide intermediate zwitterionic radicals 8 in all the highly and weak silophiles. A few of 8 occurred desilylation to produce intramolecular biradicals 9 which is the precursor of the cyclic amidol 4. Most of 8 occurred intermolecular radicals coupling to produce cyclic asymmetric dimerization compound 6. Structures of all compounds were characterized by MS （EI）, NMR data.
