This paper reviews the advancements in the site-specific activation of unmodified 1,3-dicarbonyl compounds via photoinduction, focusing on two activation mechanisms. The first involves photoinduced redox reactions, activating the α-position of the carbonyl group. The second occurs via absorption of photons in the enol form or energy transfer through a photocatalyst, leading to an excited-state transition and subsequent reactions such as 6π cyclization or the de Mayo reaction.

未修饰的 1,3-二羰基化合物光诱导生成活性中间体用于有机转化

本文综述了通过光诱导对未修饰的 1,3-二羰基化合物进行位点特异性激活的进展，重点关注两种激活机制。第一个涉及光诱导的氧化还原反应，激活羰基的 α 位。第二种是通过吸收烯醇形式的光子或通过光催化剂进行能量转移，导致激发态跃迁和后续反应，例如 6π 环化或 de Mayo 反应。
