Synthesis of 6,6′- and 6-MeO-PEG-BINOL-Ca soluble polymer bound ligands and their application in asymmetric Michael and epoxidation reactions

The first synthesis of enantioenriched Ca-bound soluble polymer BINOL ligand for the activation of asymmetric Michael addition and epoxidation reactions. This monometallic catalyst works not only as a Lewis acid but also as a Bronsted base.
