Bis(oxazoline) ligands have been used to prepare chiral catalysts for a large variety of enantioselective reactions. This versatility has attracted interest towards its immobilization, to profit from the advantages of using heterogeneous catalysis with respect to catalyst separation, possible recycl
## Abstract As shown by theoretical calculations, azabis(oxazoline)–copper complexes are considerably more stable than the analogous bis(oxazoline)–copper complexes. This enhanced stability allows them to be efficiently immobilized by means of electrostatic interactions to different anionic support
## Abstract __C__~2~‐Symmetrical boron complexes, prepared by the reactions of 2,2′‐methylenebis(oxazolines) (BOXs) with catecholborane (CATBH), can be used as catalysts (5–10 mol‐%) in the enantioselective reduction of prochiral ketones (__ee__ 72–86 %), giving the desired alcohols in satisfactory
