A redox-neutral copper-catalyzed cascade reaction involving alkoxyl radical-mediated ring expansion/1,4-difunctionalization of 1,3-enynes was developed, offering a straightforward approach to the tetra-substituted allenes with macrolactone, CN, and CF3 functional groups. Remarkably, incorporation of the NH2 group onto the 1,3-enyne moiety enabled further cyclization to give a unique scaffold containing a lactone and an indole moiety.

铜催化下烷氧基自由基介导的扩环/1,4-二官能化 1,3-烯炔
开发了一种氧化还原中性铜催化级联反应,涉及烷氧基自由基介导的扩环/1,3-烯炔的1,4-二官能化,为具有大内酯、CN和CF 3官能团的四取代丙二烯提供了直接的方法组。值得注意的是,将NH 2基团掺入1,3-烯炔部分能够进一步环化,得到含有内酯和吲哚部分的独特支架。
