The asymmetric synthesis of sulfur(IV) functionalities presents a substantial challenge given that direct catalytic methods are underexplored. In this issue of Chem, Chi and co-workers use quinine as the chiral catalyst for the asymmetric conversion of sulfinate salts to high-value sulfinate esters and sulfinamides.
