Isoquinoline ring the changes: A novel strategy for the title reaction involves ortho‐haloarylalkynes which undergo sequential intermolecular addition of N heterocycles onto alkynes and subsequent intramolecular ring closure by arylation. The process involves the use of hydroxymethyl benzotriazole as an efficient and inexpensive ligand for the CN and CC coupling reactions.
