The syntheses of the alkaloids of the ergotoxine‐group i.e. ergocristine, α‐ and β‐ergokryptine, and ergocornine, are described. Using starting material with known stereochemistry these syntheses allowed to determine the absolute configurations also at C‐2′ and C‐12′ in the peptide part, which could not be derived from analytical data. All ergot alkaloids of the peptide type possess the same stereochemical structure.
