Lewis acid, Me3SiOTf, has been shown to be a promising promoter for aza‐Michael reaction of relatively acidic primary amide with α,β‐unsaturated ketone. A sries of α,β‐unsaturated ketones was transformed to their corresponding β‐amido ketones with moderate yields under this reaction condition.

A series of b,g-unsaturated ketones were isomerized to their corresponding a,b-unsaturated ketones by the introduction of DABCO in iPrOH at room temperature. The endo-cyclic double bond (b,g-position) on ketone was rearranged to exo-cyclic double bond (a,b-position) under the reaction conditions.
