The total synthesis of the novel immunosuppressant sanglifehrin A (SFA, 1) is described. The approach is flexible, convergent, and stereoselective. The use of Paterson's aldol methodology was pivotal for the preparation of the novel, highly substituted spirolactam fragment of SFA. The 22-membered macrocyclic core of the molecule and the coupling of this fragment to the spirolactam moiety were successfully
描述了新型免疫抑制剂 sanglifehrin A (SFA, 1) 的全合成。该方法是灵活的、收敛的和立体选择性的。Paterson 的羟醛方法的使用对于制备新型的、高度取代的 SFA 螺内酰胺片段至关重要。分别使用选择性分子内和分子间 Stille 反应成功实现了分子的 22 元大环核心以及该片段与螺内酰胺部分的偶联。基于碳二亚胺的方案被用于合成三肽骨架。
