A copper-catalyzed electrophilic amination of cyclopropanols with O-benzoyl-N,N-dialkylhydroxylamines enables the synthesis of various β-aminoketones via C-C bond cleavage and Csp3-N bond formation. The mild reaction conditions tolerate several functional groups including benzoate, tosylate, expoxide, and α,β-unsaturated carbonyls.
