underwent this sulfonylation smoothly at room temperature under metal-free and chemical-oxidant-free conditions to afford indolyl arylsulfones in good to high yields. This reaction was found to tolerate a variety of functional groups, including halides and cyclopropyl, ether, ester, and aldehyde groups. It was applied to the synthesis of biologically active 5-HT6 modulators.

The enantioselective hydroarylation of 1-alkynylindoles with organoborons for the synthesis of chiral C−N atropisomers is presented. A wide variety of vinylindole atropisomers were synthesized in excellent regioselectivity, stereoselectivity (Z-selectivity), and enantioselectivity under mild reaction conditions.
