example of a polymer-supported indium Lewis acid is presented. This new heterogeneous Amberlyst 15/indium complex effectively catalyses (20 mol % based on indium) the formation of new CC as well as CS bonds through the highly regio- and stereoselective ring-opening reaction of enantiomerically pure epoxides. The easily prepared Amberlyst 15/indium Lewis acid does not require inert atmosphere conditions or
