Part of the Springer Theses book series (Springer Theses)


Ergot alkaloids and their synthetic analogs have been reported to exhibit broad biological activity. The author investigated direct construction of the C/D ring system of ergot alkaloids based on palladium-catalyzed domino cyclization of amino allenes. With this biscyclization as the key step, total synthesis of (±)-lysergic acid, (±)-lysergol and (±)-isolysergol was achieved.
