Copper–dienamine catalysis: γ-oxyamination of α,β-unsaturated aldehydes†
Abstract
A multicatalytic system composed of copper complexes and sec-amine compounds is proposed for γ-oxyamination of α,β-unsaturated aldehydes. Using copper complexes in dienamine catalysis expands the scope of the reaction to include TEMPO radicals. Furthermore, copper catalysts oxidize allylic alcohols to form α,β-unsaturated aldehydes, enabling the one-pot oxidation/oxyamination of allylic alcohols.
