黑麦有时会被一种叫做麦角菌的真菌感染。术语“麦角”是指可在收获前或收获期间收集的深色、棕色、块状体,代表我们治疗库中最引人注目的药物之一。实际上,最重要的生物碱是这些真菌的代谢产物。我们详细阐述了三种替代的全合成途径来构建麦角林骨架,其中一种适合放大生产,最终产生了 (+)-麦角酸 (32a) 和 α-麦角隐亭 (1)(方案 5 和 6)。
Rye is sometimes infected by a fungus called Claviceps purpurea. The term ergot designates the dark, brown, tuberous bodies which can be collected before or during harvesting and represent one of the most remarkable drugs of our therapeutic arsenal. Actually, the most significant alkaloids are metabolic products of these fungi. We elaborated three alternative total synthetic pathways to construct the ergoline skeleton, one of which – suitable for scaling up – finally resulted in (+)-lysergic acid (32a) and α-ergocryptine (1) (Schemes 5 and 6).
