Polymer supported bifunctional organocatalyst and Method for preparing chiral hemiesters by using the same

摘要

The present invention provides a polymer -supported bifunctional organic catalysts, their manufacture, and the chiral esters using the same Hemi relates to the manufacturing method , and more particularly prochiral compound or meso- ring in performing the asymmetric ring-opening reaction of an acid anhydride , a difunctional organic ester having a high hemicellulose effectively producing chiral enantiomer stereoselectivity to support a catalyst in the polymer relates to a method of .
