Room temperature copper-catalyzed 2-functionalization of pyrrole rings by a three-component coupling reaction
(Chemical Equation Presented) Making rings: A new Cu-catalyzed three-component coupling reaction between 1-alkynes, sulfonyl azides, and pyrrole derivatives has been developed for making 2-functionalized pyrrole rings (see scheme). This C-C bond formation offers high efficiency and selectivity, mild reaction conditions, and a wide substrate scope.
