A copper(I)/DDQ-mediated double-dehydrogenative Diels–Alder (DDDA) reaction of simple butenes with 1,4-diketones and indolones has been established for the first time. This strategy is based on a tandem double-dehydrogenation/Diels–Alder reaction from nonprefunctionalized starting materials, in which both a diene and dienophile were in situ generated via activation of fourfold inert C(sp³)–H bonds in one catalytic system.

铜（I）/ DDQ介导的芳基丁烯与1,4-二酮和吲哚酮的双脱氢Diels-Alder反应。

首次建立了由铜（I）/ DDQ介导的简单丁烯与1,4-二酮和吲哚酮的双脱氢Diels-Alder（DDDA）反应。此策略基于非预官能化原料的串联双脱氢/ Diels-Alder反应，其中通过在一个催化系统中活化四重惰性C（sp ³）-H键原位生成二烯和亲二烯体。
