A Facile Solid-Phase Synthesis of (+)-(S)-Clopidogrel
摘要:
AbstractEnantiomerically pure (+)‐(S)‐clopidogrel was prepared by solid‐phase synthesis using the commercially available Wang resin. This method offers mild reaction conditions and provides the (+)‐(S)‐clopidogrel in overall 52% yield over six steps and with optical purity of 98.0% ee.
