is described. The stereotetrad-containing building block was prepared via a Marshall-Tamaru reaction on an aldehyde obtained by organocatalysis. For a second building block, a Marshall―Tamaru reaction was used as well. The side-chain fragment containing a hydroxy δ-lactone could be obtained by intramolecular Reformatsky reaction.
描述了新型 16 元大环内酯类 leiodermatolide 的三个关键片段的合成。含有立体四分体的结构单元是通过对有机催化获得的醛进行 Marshall-Tamaru 反应制备的。对于第二个构建块,也使用了 Marshall-Tamaru 反应。通过分子内Reformatsky反应可以获得含有羟基δ-内酯的侧链片段。
