A copper-based catalytic system has been described to enable the efficient 1,4-sulfonylindolylation of 1,3-dienes with sulfonyl chloride and indoles. This protocol offers a practical method for synthesis allylsulfone-containing indole derivatives broad range compatible functionalities excellent chemo- regioselectivities. Mechanistic studies suggest that copper catalyst plays dual role initiating radicals prompting coupling in this conjugated diene-selective 1,4-difunctionalization strategy.
