The first total synthesis of incednam (1), the aglycon of antibiotic incednine (2), is described. Incednine has been reported to exhibit significant inhibitory activity against the antiapoptotic oncoproteins Bcl-2 and Bcl-xL. The synthesis of 1 commenced with the preparation of the C1−C13 subunit 3 and the C14−C23 subunit 4. The construction of the novel 24-membered macrocycle was achieved by the application
描述了incednam(1)的第一个全合成,即抗生素incednine(2)的糖苷配基。据报道,Incednine对抗凋亡的癌蛋白Bcl-2和Bcl-xL表现出显着的抑制活性。1的合成从C1-C13亚基3和C14-C23亚基4的制备开始。通过在3和4之间应用Stille偶联,然后进行内酰胺化,可实现新型24元大环化合物的构建。
