Copper-catalyzed hydroaminocarbonylation of benzylidenecyclopropanes: synthesis of γ,δ-unsaturated amides

Abstract

Herein, we have developed a copper-catalyzed hydroaminocarbonylation of benzylidenecyclopropanes under relatively mild conditions. A series of γ,δ-unsaturated amides with a broad range of functional groups were obtained in moderate to good yields. Both dialkyl-substituted and monoalkyl-substituted hydroxylamine derivatives can be applied in this transformation to give the corresponding tertiary and secondary amides successfully.
