An efficient aerobic copper(I)-catalyzed oxyamination of β,γ-unsaturated hydrazones has been developed. The methodology provides effective access to dihydropyrazole derivatives in a one-pot process utilizing dioxygen as a sustainable sacrificial oxidant. Mechanistic studies have been performed and are suggestive of an aerobic manifold via single electron transfer.
一种高效的有氧铜(I)催化β,γ-不饱和腙的氧胺化反应已经被开发出来。该方法利用氧气作为可持续的牺牲氧化剂,在一锅反应中提供了有效合成二氢吡唑衍生物的途径。已经进行了机理研究,表明该反应是通过单电子转移的有氧途径进行的。
