A copper-catalyzed reaction of oximes with diisopropyl azodicarboxylate: an alternative method for the synthesis of oxime carbonates

Abstract

A new Cu-catalyzed efficient protocol is described for the transformation of oximes to the corresponding carbonate derivatives. Diisopropyl azodicarboxylate acted as a selective new precursor for the synthesis of oxime carbonates in high yields. The O–H bond cleavage and O–C bond formation occur in the presence of a copper catalyst providing a synthetically useful process, which tolerates a wide range of functional groups.
