Synthesis of functionalized 1,2-dihydroisoquinolines via multicomponent one-pot reaction of 2-alkynylbenzaldehyde, amine, zinc, and allylic bromide or benzyl bromide.
A multicomponent one-pot reaction of 2-alkynylbenzaldehydes, amines, zinc, and allylic bromide or benzyl bromide using the combination of Mg(ClO4)2/Cu(OTf)2 as catalyst in THF/DCE (1:20) is described, which provides an efficient and practical route for the synthesis of functionalized 1,2-dihydroisoquinolines.
