Abstract

A novel copper-catalyzed complete diastereoselective 1,2-difunctionalization of oxabicyclic alkenes has been developed. Two C-S bonds were constructed simultaneously on the oxabenzonorbornadienes leading to β-thiocyanato thioethers through the three-component (oxabicyclic alkenes, aryl iodides, and potassium thiocyanate), one-pot reaction. Various functional groups attached to the substrates were tolerated in this protocol to afford the corresponding β-thiocyanato thioether products in moderate yields.
