Abstract: 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… read more here.
