Spiroketal diol 1 was prepared from 5, which can be obtained by enantio-selective enzymatic acetylation of meso diol 6, in 12 steps in 16.5% total yield and its regioselective protection was achieved by an enzymatic method to give 16 in high yield.
由5制备螺碳基二醇1,其可以通过内消旋二醇6的对映选择性酶促乙酰化获得,以12个步骤,总收率为16.5%,并且通过酶促方法实现了其区域选择性保护,从而以高收率获得了16。
