The endo-cyclic double bond (β,γ-position) on ketone was rearranged to exo-cyclic double bond (α,β-position) under the reaction conditions.20130710 已補正 by yuchi;tku_id: 000062828;Made available in DSpace on 2013-07-29T05:39:50Z (GMT).

The β-amino ketone was obtained as the major product from a reaction mixture of β,γ-unsaturated ketone, AlCl3 and Ts-NH2 in CH2Cl2 at room temperature. This Lewis acid promoted β-substitution reaction mechanism was proposed as that the process occurred via in situ isomerization of β,γ-unsaturated ketone to α,β-unsaturated ketone followed by the 1,4-addition reaction.tku_id
