Two common approaches to heteroaromatic methyl sulfones exit. Both routes rely on the modification of the already installed functional groups: (a) oxidation of the thiomethyl group; 4 and (b) metal-mediated cross-coupling of halides/boronates with sodium sulfinate or sulphur dioxide/methyl iodide (Figure ). Here, we present a principally novel approach to methyl sulfones that relies on the 1,3-heterocycle disconnection logic with the newly developed reagent 1 (Figure ).
