An Ir-catalyzed diastereoselective hydrogenation was employed to establish the stereogenic center at carbon atom C14 of a C9-C21 fragment of geldanamycin. The fragment was stereoselectively synthesized from d-mannitol in 18 steps.
利用铱催化的非对映选择性氢化反应,在格尔德霉素的 C9-C21 片段的碳原子 C14 上建立了立体中心。该片段由 d-mannitol 经过 18 个步骤立体选择性合成。
