A mild and convenient method has been developed for the construction of 3-arylcoumarins through a CuI-catalyzed reaction of coumarins with arylamines under mild conditions.
A mild and convenient method has been developed for the construction of 3-arylcoumarins through CuI-catalyzed reaction of coumarins with arylamines under mild conditions. The present protocol simply utilizes readily available starting materials as substrates, inexpensive metal as catalyst, providing various 3-arylcoumarins with good functional groups toleration in moderate to good yields. Moreover, control experiments show that the reaction proceeds by a radical pathway.
