desymmetrization of cyclic anhydrides is carried out using dihydroxy compounds. A mild route to synthesize fused saturated/unsaturated macrocyclic tetralactones with different ring sizes (20-34) having a wide variety of spacers is described. The structure is confirmed by the representative single-crystal X-ray analysis. The multiple reduction of unsaturated macrocyclic tetralactones is also illustrated. This method
[反应:见正文]使用二羟基化合物进行环状酸酐的脱对称化。描述了合成具有不同间隔基的具有不同环尺寸(20-34)的稠合的饱和/不饱和大环四内酯的温和路线。通过代表性的单晶X射线分析确认了该结构。还示出了不饱和大环四内酯的多次还原。该方法温和,选择性和高效,并且可以实现高收率。
