A reaction mixture of β,γ-unsaturatedketone and BF 3 .OEt 2 in CH 3 OH was stirred at room temperature and β-methoxy ketone was produced in high yield. The β-amino ketone was obtained as the major product from a reaction mixture of β,γ-unsaturatedketone, AlCl 3 and Ts-NH 2 in CH 2 Cl 2 at room temperature. This Lewis acid promoted β-substitution reaction mechanism was proposed as that the process

A series of β,γ-unsaturated ketones were isomerized to their corresponding α,β-unsaturatedketones by the introduction of DABCO in iPrOH at room temperature. The endo-cyclic doublebond (β,γ-position) on ketone was rearranged to exo-cyclic doublebond (α,β-position) under the reaction conditions.

acid-promoted reaction condition of β,γ-unsaturated ketone with indole was developed for the synthesis of 3-substituted indoles with moderate to good yields. A Lewis acid such as AlCl3 was shown to be a promising promoter for in situ isomerization of β,γ-unsaturated ketone to its corresponding α,β-unsaturated ketone, then undergoing Friedel–Crafts Michael addition reaction with indole to afford 3-substituted
