Synthesis of the highly substituted polyoxygenated tetrahydropyran ring of botcinic acid, the revised structure of botcinolide is achieved using, as key steps, a highly stereoselective aldol reaction of the titanium enolate from a lactate-derived chiral ketone and a stereoselective dihydroxylation.
合成了高取代度的植物酸多氧合四氢吡喃环,通过使用乳酸酯衍生的手性酮的烯醇钛的高度立体选择性醛醇缩合反应和立体选择性二羟基化反应作为关键步骤,实现了肉毒杆菌酯的修饰结构。
