REFERENCES

• Pd-catalyzed coupling of acetylenes with iodoaromatic compounds with in situ cyclization has been employed as a route to various heterocycles. Several examples were reported with this alkyne in which a substituted oxygen heterocycle was obtained with good regioselectivity from o-iodo phenols, o-iodo benzyl alcohols or o-iodobenzoic acid derivatives: J.
