Enantioselective Copper-Catalyzed Electrophilic Sulfenylation of Cyclic Imino Esters

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.

Regioselective cobalt-catalyzed addition of sulfides to unactivated alkenes

A novel method to synthesize tertiary alkyl/aryl sulfides in a mild and regioselective manner from unactivated alkenes using cobalt catalysis is described. The methodology is compatible with sensitive functionalities and is successful with several different types of alkenes and sulfides.

Reaction of Thio Acid S-Esters with p-Toluenesulfonic Acid: A Facile Synthesis of p-Toluenethiosulfonic S-Esters

Treatment of dehydrated p-toluenesulfonic acid (TsOH) with thio acid S-esters such as carbothioic acid and phosphorus thio acid S-esters in refluxing solvent resulted in the formation of p-toluenethiosulfonic S-esters (TsSR).The reaction of trialkyl phosphorotrithioites with TsOH provided the corresponding TsSR in relatively good yields.This constitutes a new and facile method for the preparation of unsymmetrical thiosulfonic S-esters.Keywords-p-toluenesulfonic acid; trialkyl phosphorotrithioite; trialkyl phosphorotrithiolate; carbothioic acid S-ester; p-toluenethiosulfonic S-ester; dialkyl disulfide.
