The use of a new, insoluble polymer-bound bis(oxazoline) ligand (IPB-box) for the copper-catalyzed heterogeneous enantioselective glyoxylate-ene reaction is described. Good activity and ee values in the range 85-95% have been obtained during five to seven recycles, either in batch mode or under flow conditions, demonstrating also the recovery and reuse of the whole catalytically active copper complex.

Abstract
The use of a new, insoluble polymer-bound bis(oxazoline) ligand (IPB-box) for the copper-catalyzed heterogeneous enantioselective glyoxylate-ene reaction is described. Good activity and ee values in the range 85-95% have been obtained during five to seven recycles, either in batch mode or under flow conditions, demonstrating also the recovery and reuse of the whole catalytically active copper complex.File in questo prodotto:
