The phorboxazole natural products are among the most potent inhibitors of cancer cell division, but they are essentially unavailable from natural sources at present. Laboratory syntheses based upon tri-component fragment coupling strategies have been developed that provide phorboxazole A and analogues in a reliable manner and with unprecedented efficiency. This has been orchestrated to occur via the
佛盒唑天然产物是癌细胞分裂最有效的抑制剂之一,但目前基本上无法从天然来源获得。已经开发了基于三组分片段偶联策略的实验室合成,以可靠的方式和前所未有的效率提供佛盒唑 A 和类似物。这是通过从两个丝氨酸衍生的酰胺依次或同时形成天然产物的两个恶唑部分来进行的,包括氧化-环化脱水。已经开发了代表碳 3-17、18-30 和 31-46 的三种预组装组件的优化制备。本文详细介绍了这三个基本构建块的设计和综合。
