Herein, we developed a practical method for synthesizing a class of novel and highly valuable indolyl vinyl sulfonyl fluorides. This protocol has carved out a path for constructing a broad range of vinyl sulfonyl fluorinated indoles with exclusive stereo- and regioselectivity through the Friedel-Crafts/elimination reaction without any transition-metal catalyst. This transformation features mild conditions, high efficiency, excellent selectivity, and rich substrate compatibility, highlighting its significant value in medicinal chemistry and many related disciplines.
