摘要

Abstract: Copper-catalyzed coupling reaction of 2-iodobenzoic acids and alkynes such as terminal acetylenes, alkynyl carboxylic acids, and trimethylsilylacetylene selectively afforded isocoumarins and phthal-ACHTUNGTRENNUNGides in the presence of cesium carbonate (Cs2CO3) and dimethyl sulfoxide (DMSO). Among the regioselective products, only the 6- endo-dig product, isocoumarin, was formed at 1008C, and the 5-exo-dig product, ...
