In the case of asymmetric hydride transfer, polythiourea was proven to be more efficient for ruthenium-catalyzed reduction of arylketones, although the iridium complexes gave rise to higher ee when using amino sulfonamide bound to a polystyrene matrix. In the case of asymmetric reduction, the modification of the binap allows the formation of a polymer that could be used as a catalyst precursor and exhibits enantioselectivities as high as observed in solution, but easier to separate and recycle. Bisoxazoline bound to silica particules could also be used in copper-catalyzed asymmetric Diels-Alder reaction and cyclopropanation with selectivities similar to that obtained in solution. © 2013 Walter de Gruyter GmbH, Berlin/Boston Pure and Applied Chemistry De Gruyter 76/3(2004-01-01), 679-688 0033-4545 76:3<679 2004 76 pac https://doi.org/10.1351/pac200476030679 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1351/pac200476030679 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Lemaire Marc Laboratoire de Catalyse et Synthese Organique UCBLCNRS, UMR 5622, CPE, 43 boul.11 Novembre, 69622 Villeurbanne Cédex, France NATIONALLICENCE 773 0- Pure and Applied Chemistry De Gruyter 76/3(2004-01-01), 679-688 0033-4545 76:3<679 2004 76 pac CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
