A new practical and concise total synthesis of enantiopure camptothecin and SN-38 (14% overall yield, 99.9% ee and 99.9% purity) was described, starting from inexpensive and readily available materials. The development of column chromatography-free purification was achieved in all steps, which offers an economic industrial process to the camptothecin-family alkaloids.
从廉价易得的材料开始,描述了一种新的实用,简明的对映体喜树碱和SN-38的全合成(总收率14%,ee 99.9%和纯度99.9%)。在所有步骤中都实现了无柱色谱纯化的发展,这为喜树碱家族生物碱提供了经济的工业生产方法。
