The synthesis of the C(18)−C(34) fragment of amphidinolide C has been achieved via two routes, culminating in both the shortest (11 steps) and highest yielding (26% overall yield) approaches to this segment. The highly convergent approach will facilitate the synthesis of analogues, including the C(18)−C(29) fragment of amphidinolide F. Synthetic highlights include the selective methylation of a diyne
安非他命C的C(18)-C(34)片段的合成已通过两条途径完成,最终以最短(11个步骤)和最高收率(26%的总收率)的方式达到了这一段。高度收敛的方法将有助于合成类似物,包括两性霉素F的C(18)-C(29)片段。合成亮点包括二炔的选择性甲基化,以及第二代钴催化剂的高效使用。 Mukaiyama氧化环化形成反式-THF环。
