Abstract

A novel and highly efficient dehydrogenative cross-coupling­ reaction between α-amino carbonyl compounds and azoles by copper catalysis using di-tert-butyl peroxide (DTBP) as an oxidant is described­. A diverse range of azoles undergo the dehydrogenative imidoylation smoothly with various α-amino carbonyl compounds for the exclusive formation of the corresponding N-imidoyl azoles in high yields under air. The synthetic method has the advantages of good functional-group tolerance, wide substrate scope, excellent yields, and simple operation­, thus providing a convenient and practical protocol for the synthesis of functionalized azoles.
