A meso-1,4-enediol bis-silyl ether 2 having bicyclo[2.2.1]heptene background has been transformed diastereo- and enantioselectively into (−)-malyngolide 1, an antibiotic isolated from the blue-green marine algae, Lyngbya majuscula, via Rh(I)-(R)BINAP-catalyzed asymmetrization and diastereoselective modification of the optically active product thus obtained.
具有双环[2.2.1]庚烯背景的内消旋-1,4-烯二醇双甲硅烷基醚2已非对映和对映选择性转化为(-)-malyngolide 1,这是一种从蓝绿色海藻Lyngbya majuscula中分离出来的抗生素,通过的Rh(I) - ([R如此获得)BINAP催化asymmetrization和光学活性产物的非对映选择性修饰。
