-
Paragraph 0010; 0023; 0024; 0025, (2019/07/16)
The invention relates to a resolution method of droxidopa threo type key intermediates (key intermediate I, key intermediate II and key intermediate III in synthetic routes 1, 2 and 3), which is characterized in that a non-alkaloid, commercially available
A PROCESS FOR THE PREPARATION OF DROXIDOPA
-
, (2016/10/04)
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.
