A reaction between terminal alkynes and sulfonamides under ambient air using PIDA (diacetoxy iodobenzene) provides α-sulfonylamino ketones. This metal-free reaction offers a broad substrate scope, excellent regioselectivity, easily accessible reactants, and mild reaction conditions and is operationally simple.
