有机光化学反应因其污染小、选择性高、反应条件温和等优势，而备受关注，成为近年的研究热点之一。本项课题以设计合成的结构新颖的有机小分子为反应底物，通过研究其在不同反应条件下的光化学反应行为和反应机理，发展环境友好、高效合成重要有机中间体的光化反应新途径。主要研究内容包括：通过γ,δ-环氧芳基酮类化合物的光化学反应研究，探讨环氧化合物的新光化学反应行为，以及合成α,β-不饱和半缩醛化合物的新方法；利用光化学重排/Diels-Alder 加成串联反应捕捉肉桂酸衍生物光化学反应中间体实现多取代苯并环己酮类化合物的合成；利用环丙基自由基易于重排开环的特点，一步反应合成具有多个手性中心的螺[4,5]癸烷化合物，并通过引入手性辅助剂，实现固相和液相状态下的不对称光化学合成。通过以上工作的开展探索有机光化学反应研究的新领域，拓展有机光化学反应在合成中的应用。

Organic photochemical reactions play an important role in the context of green chemistry and total synthesis. The photon involved in the procedure can be considered as the ideal clean reagent for organic synthesis in contrast to toxic chemical activators. Therefore, the field of organic photochemical reactions has received considerable interests from both academy and industry. Based upon our previous work, we are continuing to explore new photochemical reactions including photochemical studies on aromatic γ,δ-epoxy ketone compounds, photochemical synthesis of benzocyclohexanones through a photochemical rearrangement/Diels-Alder cascade reaction, as well as asymmetric photochemical synthesis of spiro[4,5]decanes. The research work will enhance the topic of investigations on organic photochemistry and highlight the application of photochemistry in the realm of organic synthesis.
