As an extension of our earlier structure/activity investigation of resveratrol (1a) cancer cell growth inhibitory activity compared to the structurally related stilbene combretastatin series (e.g., 2a), an efficient synthesis of E-stilstatin 3 (3a) and its phosphate prodrug 3b was completed. The trans-stilbene 3a was obtained using a convergent synthesis employing a Wittig reaction with phosphonium
作为我们早期对白藜芦醇 ( 1a ) 癌细胞生长抑制活性与结构相关的芪康布他汀系列 (例如,2a )相比的结构/活性研究的延伸,E- stilstatin 3 ( 3a ) 及其磷酸盐前药3b的有效合成完成了。的反式均二苯乙烯3A使用采用与溴化鏻进行Wittig反应汇集合成,得到9作为关键反应步骤。Z-甲硅烷基醚13 的脱保护得到E- stilstatin 3 ( 3a) 作为独家产品。3a的结构和立体化学通过 X 射线晶体结构测定得到证实。
