A concise enantioselective synthesis of malyngamide W (1) and its 2′-epimer was described. The strategy was based on three key steps: (1) ozonolysis of compound 11 which was derived from (R)-(−)-carvone 8, followed by copper-iron-catalyzed rearrangement to give the key cyclohex-2-enone intermediate 5, (2) Nozaki–Hiyama–Kishi coupling reaction between aldehyde 4 and iodide 14 to afford alcohol 3, and
简明的对映体合成 麦芽酰胺W描述了(1)及其2'-顶基。该策略基于三个关键步骤:(1)臭氧分解源自(R)-(-)-香芹酮8的化合物11,然后进行铜铁催化重排,得到关键的环己-2-烯酮中间体5,(2)醛4和碘化物14之间的Nozaki–Hiyama–Kishi偶联反应得到醇3,(3)化合物21中酮官能团的不对称(R)-CBS还原,以建立C-2'手性中心。目标化合物1。的绝对配置麦芽酰胺W因此(1)通过1和2'- epi - 1的合成得以证实。
