A series of β,γ-unsaturated ketones were isomerized to their corresponding α,β-unsaturated ketones by the introduction of DABCO in iPrOH at room temperature. The endo-cyclic double bond (β,γ-position) on ketone was rearranged to exo-cyclic double bond (α,β-position) under the reaction conditions.
通过在室温下在 iPrOH 中引入 DABCO,将一系列 β,γ-不饱和酮异构化为相应的 α,β-不饱和酮。在反应条件下,酮上的环内双键(β,γ-位)重排为环外双键(α,β-位)。
