Abstract

The 1st example of a polymer-supported In Lewis acid is presented. This new heterogeneous Amberlyst 15/In complex effectively catalyzes (20 mol % based on In) the formation of new C-C as well as C-S bonds through the highly regio- and stereoselective ring-opening reaction of enantiomerically pure epoxides by indoles and 2-naphthalenethiol, resp. The easily prepd. Amberlyst 15/In Lewis acid does not require inert atm. conditions or anhyd. media and can be easily recovered and recycled for several times without loss of activity.
