Abstract
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.
