Popis: A facile protocol to construct β-selective allylic 1, 2-dihydroisoquinoline with high E/Z selectivity from its γ-regioisomer through an unexpected Lewis base or thermo-initiated rearrangement is described. This rearrangement transformation proceeds under mild reaction conditions with efficiency and atom economy. The control experiments demonstrated that these rearrangement processes initiated by different modes followed two distinct mechanisms.
