A highly stereocontrolled total synthesis of the cytotoxic marine macrolide aplyronine C is described. The route exploits aldol methodology to install the requisite stereochemistry and features a crucial boron-mediated aldol coupling of an N-vinylformamide-bearing methyl ketone with a macrocyclic aldehyde to introduce the full side chain. The synthesis of two novel C21-C34 side chain analogs is also reported.
本文描述了具有高立体选择性的细胞毒海洋大环内酯阿普洛宁 C 的全合成。该路线利用 aldol 方法学来构建所需的立体化学,并具有一个关键的硼介导的 N-乙烯基甲酰胺取代的甲基酮与大环醛的 aldol 偶联反应,以引入完整的侧链。还报道了两种新型 C21-C34 侧链类似物的合成。
