Methods are reported for the efficient assembly of a series of phenol-derived propiolates, including the parent system 56, and their Au(I)-catalyzed cyclization (intramolecular hydroarylation) to give the corresponding coumarins (e.g., 1). Simple syntheses of naturalproducts such as ayapin (144) and scoparone (145) have been realized by such means, and the first of these subject to single-crystal
