A new and simple method for a formal synthesis of (±) -lysergic acid (1), via a four-step sequence starting from the aldehyde (13), is described. A very high yield of the product was obtained after purification by column chromatography at the end of the process, without isolation of intermediates.
描述了一种新的简单方法,通过从醛(13)出发的四步反应形式合成(±)-
麦角酸(1)。在过程结束时,通过柱层析纯化获得了非常高的产率,而无需分离中间体。
