The copper-promoted reaction of β-lactams with t-butyl perbenzoate results in benzoyloxylation of the azetidin-2-one ring at the C-4 position. There is no competing reaction at the C-3 position, but reaction at exocyclic carbon α to nitrogen competes with ring substitution.
β-内酰胺与过苯甲酸叔丁酯的铜促进反应导致氮杂环丁烷-2-酮环在C-4位的苯甲酰氧基化。在C-3位没有竞争反应,但是环外碳α与氮的反应与环取代竞争。
