发明名称 A PROCESS FOR THE PREPARATION OF DROXIDOPA
摘要 The present invention provides a novel process for the preparation of droxidopa, a synthetic amino acid precursor of norepinephrine. The process is a stereoselective process for the preparation of droxidopa using asymmetric induction and thus avoids synthetic process involving chiral resolution. The present invention also provides novel intermediates of formula V and formula VI.
