including ester, α,β‐unsaturatedester, uncongested ketone groups, as well as enol derivatives of acetaldehyde such as enol ether and enamides. The electrophilic partner has been extended from N‐(2,6‐dimethylphenyl) and N‐methyl amides to N‐n‐butyl, and N‐cyclohexyl amides. The results demonstrated that the method can be used to synthesize a number of functionalized α,β‐unsaturated ketimines and α,β‐enones
