consecutive Sonogashira and cascade Pd‐catalyzedheterocyclization/oxidativeHeckcouplings from readily available ortho‐iodosubstituted phenol, aniline, and benzamide substrates, alkynes, and functionalized olefins. The cyclization of O‐ and N‐heteronucleophiles follows regioselective 5‐endo‐dig‐ or 6‐endo‐dig‐cyclization modes, whereas the subsequent Heck‐type coupling with both mono‐ and disubstituted

cyclization–coupling cascade reactions between ortho-alkynylarylcarboxamides and methyl vinyl ketone or acrylaldehyde are described. An initial 6-endo-oxypalladation of the triple bond is followed by a C–C coupling to give structurally diverse isochromenimines (and related heterosubstituted derivatives), in which the α,β-unsaturated carbonyl moiety is incorporated as an alkyl-type exocyclic side chain. The coupling
