(Chemical Equation Presented) 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 C - N and C - C coupling reactions.
