The conjugate addition of phenylselenomethyl-lithium to the α,β-unsaturated lactone (4) was a key step in a short synthesis of (±)-benzoylselenopederic acid (2); union of (2) and (±)-benzoylpedamide (3) by a modification of known procedures gave (±)-pederin (1).
共轭加成phenylselenomethyl
锂的对α,β不饱和内
酯(4)是(±)-benzoylselenopederic酸的短合成(一个关键步骤2); 通过改进已知方法将(2)和(±)-
苯甲酰pedamide(3)结合,得到(±)-pederin(1)。
