Photoinduced Single Electron Transfer Reactions For The Synthesis Of Heterocyclic Compounds

The reaction that photoinduced electron to transfer into cyclization has the featureof high yield and good regioselectivity. Simultaneously, the reaction does not require themetallic electron as template or a high dilution condition. The research of the paper isbased on the theory of photoinduced electron transfer. We design to synthesize differentphotoreactions of multi-electron donor imide system, aiming at providing evidences forthe electron transfer process of complex compounds under excited condition.In the research, we synthesized six new N-（ω-trimethylsilylmethoxy）phthalimideand N-（α-ethoxycarbonyl）phthalimide photoreaction substrates which regardphthalimide as electron receptor and the trimethylsilyl ether chain or ester chainincluded in the termination as electron donor. The implementing method was used byphotoreaction in methanol. Consequently, we got six new macrocydic compounds. Thestructures of all the final products and intermediate products were validated by¹H-NMRand¹³C-NMR.
