摘要:The (S)-2-Chlorophenylglycine Moiety Is Well Recognized In The Structure Of (S)-Clopidogrel,A Known Antithrombotic Drug. We Prepared An Enantiomerically Pure Chiral Building Block Via An Enzyme-Catalyzed Resolution Of (Rs)-N-Boc-2-Chlorophenylglycine Methylester. The Best Results Were Obtained By Means Of An Immobilized Subtilisin,The Cross-Linked Enzyme Aggregate (Alcalase-Clea (R)). The High Enantiomeric Excess Of The Synthon Obtained Remained The Same Over The Course Of Clopidogrel Synthesis; The Simplicity Of The Process Makes This Pathway Suitable For Large-Scale Preparation.
