A convergent, stereoselective synthesis of a brefeldin C lactam analogue is described. Novel features are application of the asymmetric iridium-catalyzed allylic substitution on a multigram scale for construction of the stereogenic centers C-9 as well as C-15 and an intermolecular Nozaki-Hiyama-Kishi reaction for introduction of the brefeldin enoate moiety.
本文介绍了一种收敛、立体选择性的brefeldin C内酰胺类似物的合成方法。创新之处在于:大规模应用手性铱催化下的烯丙基取代反应来构建手性中心的C-9和C-15,以及采用分子间Nozaki-Hiyama-Kishi反应引入brefeldin烯酸酯部分。
