Gold-Catalyzed Addition of Sulfonic Acids to Alkynes

摘要

Alkenyl sulfonates are importantbuilding blocks in synthetic chemistry, especiallyas electrophiles in cross-coupling reactions. Theauthors developed a new gold-catalyzed additionof sulfonic acids to alkynes to provide alkenyl sul-fonates. The reaction proceeds under mild condi-tions with high regio- and stereoselectivity.
