  摘要：

  A new method for the synthesis of n-(3-acyloxypropyl)-substituted six- to thirteen-membered alkan-n-olides was developed. The method is based on the H2SO4-catalyzed reactions of oxabicycloalkenes, obtained from 2-(3-acetoxypropyl)cycloalkanes, with H2O2 and formic or acetic acid. The method includes the subsequent transformations of oxabicycloalkenes; into bicyclic hydroperoxides, peroxy ethers, and, at the final stage, into target lactones formed in 56-71% yields. These transformations are carried as a one-pot reaction.

  An efficient alkoxyl radical-triggered ring expansion/cross-coupling cascade was developed under cheap metal catalysis. Through the metal-catalyzed radical relay strategy, a wide range of medium-sized lactones (9–11 membered) and macrolactones (12, 13, 15, 18, and 19-membered) were constructed in moderate to good yields, along with diverse functional groups including CN, N3, SCN, and X groups installed

  在廉价金属催化下开发了一种有效的烷氧基自由基触发的扩环/交叉偶联级联。通过金属催化的自由基中继策略，以中等至良好的产率构建了各种中型内酯（9-11元）和大环内酯（12、13、15、18和19元），以及多种同时安装的功能组包括CN、N 3、SCN和X组。密度泛函理论（DFT）计算表明，环烷基-Cu（III）物质的还原消除是交叉偶联步骤更有利的反应途径。基于实验和DFT的结果，提出了用于该串联反应的Cu( I )/Cu( II )/Cu( III )催化循环。

  A photoinduced copper-catalyzed alkoxyl triggered C−C bond cleavage/aminocarbonylation cascade is presented. Through adjusting the structure of alkoxyl radical precursors, functionalized lactones and keto-amides were synthesized with good yields and excellent functional group tolerance under redox-neutral conditions. Notably, this protocol enables the integration of lactone fragments with many amine
