Fig. 1: Stereogenic-at-sulfur compounds and methods for their synthesis.

a Examples of stereogenic-at-sulfur compounds used as pharmaceuticals, agrochemicals and in asymmetric synthesis/catalysis. b Wei and coworkers25: enantioselective synthesis of sulfinamides and sulfinate esters using bifunctional 4-arylpyridine N-oxide organocatalysts. c Robinson and coworkers33: sulfide to sulfoxide oxygenation using a UPO. d This work: enantioselective sulfoximine synthesis via the UPO catalysed oxygenation of sulfilimines, using a kinetic resolution approach. e This work: enantioselective synthesis of sulfinimine enantiomers via the UPO catalysed oxygenation of sulfenimines.
