A synthesis of the C1-C15 fragment of dolabelide C is reported. The key step is a diastereoselective Mukaiyama aldol reaction to form the C6-C7 bond, followed by reduction and deoxygenation of the carbonyl group at C5. The trisubstituted vinyl iodide is introduced via the corresponding vinyl boronate by cross metathesis.
报告了一种多拉贝尔内酯 C 的 C1-C15 片段的合成方法。关键步骤是通过非对映选择性的 Mukaiyama 醛醇反应形成 C6-C7 键,然后对 C5 处的羰基进行还原和脱氧。通过交叉偏析作用,相应的乙烯基硼酸酯引入了三取代的碘化乙烯基。
