A novel, scalable approach to the C14–C23 fragment of eribulin mesylate is disclosed. Key 2,3-Wittig rearrangement is strategically effected via [Rh] mediated decomposition of 1,2,3-triazole intermediate to derive the 2,5-trans-tetrahydrofuran motif, enabling multi-kilogram access to the desired C14–C23 fragment.
公开了一种新的、可扩展的方法来处理甲磺酸艾日布林的 C14–C23 片段。关键的 2,3-Wittig 重排是通过 [Rh] 介导的 1,2,3-三唑中间体分解产生 2,5-反式-四氢呋喃基序的策略性影响,从而使数公斤级的物质能够接触到所需的 C14-C23 片段。
