| 中文摘要: |
| 可见光诱导反应与廉价金属催化是绿色合成的两个重要策略,其教学转化对推动化学实验教学改革具有重要意义。本研究基于“科研反哺教学”理念,开发了可见光诱导与铜催化协同的硫叶立德[4+1]环加成教学实验。该反应通过光诱导卡宾转移原位生成硫叶立德,高效构建吲哚啉骨架(收率82%),体现了绿色合成的协同优势。实验涵盖无水无氧操作、TLC监测、柱层析纯化及HRMS/NMR表征等核心技能,强化了学生对光化学与铜催化机制的理解,并为前沿科研成果向教学转化提供了实践范例。 |
| 英文摘要: |
| Visible-light-induced reactions and base-metal catalysis are two important strategies in green synthesis. Integrating these strategies into teaching is highly significant for advancing chemical education reform. Guided by the "research-to-teaching" philosophy, this study developed a teaching experiment based on a visible-light-induced/copper-catalyzed [4+1] cycloaddition employing sulfur ylides. This reaction efficiently constructs indoline scaffolds with an 82% yield through photoinduced carbene transfer, generating sulfur ylides in situ and demonstrating the synergistic benefits of green synthesis. The experimental procedure incorporates key techniques, such as Schlenk operations, thin-layer chromatography (TLC) monitoring, flash column chromatography, and high-resolution mass spectrometry (HRMS) and nuclear magnetic resonance (NMR) characterization. These techniques effectively enhance students" understanding of photochemical and copper-catalyzed processes. This work provides a practical model for translating cutting-edge research findings into educational applications. |
