The feasibility of catalystcontroloverthreefoldstereogenicC−S atropisomers is reported. A catalytic oxidation sequence of triptycyl thioethers via sulfoxides to sulfones with a stereogenic C(sp3)−S axis proceeds with high levels of enantio- and diastereocontrol, while stereodivergence was possible to address each of the three atropisomers.
