Synthesis of 6,6'- and 6-MeO-PEG-BINOL-Ca soluble polymer bound ligands and their application in asymmetric Michael and epoxidation reactions
Design and synthesis of a flexible spacer attached 6-MeO-PEG-BINOL ligand has been described. The enantioenriched Ca soluble polymer bound ligand (SPB-II) was generated utilizing easily available, eco-friendly CaCl2, and applied for C-C as well as C-O bond forming reactions. The ligand was precipitated adding diethylether, and the same ligand was used with equal efficiency for two more cycles. (c) 2004 Elsevier B.V All rights reserved.
