Herein we report an enantioselective sulfenylation of cyclic imino esters with the efficient and versatile sulfenylation reagent S-alkyl 4-methylbenzenesulfonothioates. By utilizing the Cu/tBu-Phosferrox catalytic system, we can assemble diverse S-alkyl groups into the cyclic imino esters under mild conditions in good yields and with excellent enantioselectivities. Remarkably, this method demonstrates a high tolerance of diverse functional groups and proves to be applicable in the late-stage functionalization of pharmaceuticals.

A simple and efficient visible-light mediated synthesis of thiosulfonates via a radical-radical coupling of sulfenyl radicals and arylsulfonyl radicals was developed. The reaction of thiols, aryldiazonium tetrafluoroborates and DABSO proceeded at room temperature using 5 mol% eosin Y. The reaction displayed wide functional group tolerance and delivered the unsymmetrical thiosulfonates in good to excellent yields.

Thiosulfonates were prepared by the iodine oxidative sulfenylation of sulfinates with various disulfides in good yields both in the presence and absence of solvent. One of the important biological applications of sulfenylation is the reaction of cyclic disulfides.
