A copper-catalyzed four-component formal oxyaminalization of alkenes with Togni’s reagent and amines using molecular oxygen as both the oxidant and oxygen source has been developed for the first time, offering a straightforward and efficient method for the synthesis of a range of structurally diverse α-oxoketene aminals. The use of cheap copper catalyst and readily available substrates, excellent functional
