Synthesis of the polyoxygenated nonalactone ring of 2-epibotcinolide was achieved using a highly stereoselective aldol reaction of the titanium enolate from a lactate-derived chiral ketone, a stereoselective dihydroxylation and a Yamaguchi macrolactonization reaction.
使用来自乳酸酯的手性酮的烯醇钛的高度立体选择性的醛醇缩合反应,立体选择性的二羟基化和山口的大内酯化反应,实现了2-表肉毒酚内酯的多加氧非内酯环的合成。
