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.
从N-新戊酰-Uhle的酮开始,已开发出一种新的麦角灵骨架合成方法。四环骨架的环D是由二酯的分子内狄克曼缩合形成的,该二酯是在N-新戊酰基Uhle的酮的适当取代的衍生物的Reformatsky反应中得到的,然后消除水。
