Polymer-supported linked-BINOL was synthesized to immobilize asymmetric catalysts with two BINOL units. The advantage of the polymer-supported linked-BINOL over randomly polymer-supported BINOL was confirmed by asymmetric Michael reaction. A novel polymer-supported La-Zn-linked-BINOL complex afforded the Michael adduct in good yield and moderate ee. (C) 2000 Elsevier Science Ltd. All rights reserved.
