| Abstract: | Starting from N-pivaloyl-Uhle's ketone a new synthetic approach to the ergoline skeleton has been elaborated. Ring D of the tetracyclic skeleton was formed by an intramolecular Dieckmann-condensation of a diester, obtained in a Reformatsky reaction of a properly substituted derivative of N-pivaloyl Uhle's ketone followed by elimination of water. |
