摘要/Abstract

报道了一种紫外光引发的芳基醛或芳基酮与炔烃的环化反应来构筑茚酮化合物. 该反应具有效率较高、原子经济性高、原料简单易得、环境友好、底物适应性较强等优势, 在紫外光照射, 氧气为氧化剂, 无光催化剂的条件下可以顺利进行.
关键词: 紫外光, 环化反应, 无光催化剂, 茚酮
The first UV-light-initiated cyclization of aryl aldehydes or aryl ketones with alkynes has been developed for the preparation of indenones. This reaction could proceed smoothly under UV-light with O₂ as an oxidant and photocatalyst-free condition, which features high efficiency, high atom economy, easily available starting materials, environmental friendliness, and tolerance to broad functional groups.
Key words: UV-light, cyclization, photocatalyst-free, indenones
