摘要

For the use of analytics, European pharmacopoeial impurities A, B, C, and D of cabergoline were synthesized. Ergocryptine was chosen as a starting material and synthesis was accomplished via two approaches, different in length and stereochemical outcome. A longer, indirect approach was realized through otherwise problematic oxidations of the 9, 10- dihidrolysergol derivative, to the corresponding aldehyde and carboxylic acid. This was ...
