Phosphate-Modulated Asymmetric Copper Catalysis for Photochemical Enantioselective S-Benzylation of Sulfenamides.
S-stereogenic sulfilimines constitute valuable S(IV)-based scaffolds widely encountered in chiral ligands, pharmaceuticals, and bioactive molecules, yet their catalytic enantioselective construction remains a formidable challenge. Herein, we report a versatile copper catalytic platform assembled from a chiral pyridine-...
