2007 (English)In: Advanced Synthesis and Catalysis, ISSN 1615-4150, E-ISSN 1615-4169, Vol. 349, no 13, 2079-2084 p.Article in journal (Refereed) Published
A pyridine-bis(oxazoline) ligand was efficiently immobilized by copper(I)-catalyzed azide-alkyne cycloaddition onto a polystyrene resin. The so obtained click-pybox resin 1a was associated with various metal salts (YbCl3, LuCl3, CuOTf) and the resulting resin-bound catalysts were explored in ring-opening of cyclohexene oxide, silylcyanation of benzaldehyde and alkynylation of imines. These new polymer-supported catalysts exhibit good to excellent performances in terms of catalytic activity, enantioselectivity and recyclability.
