RCM+AD=T2: In the presence of the C16‐methylene group, regioselective ring‐closing metathesis (RCM) formed the (12E)‐endocyclic double bond, which underwent Os‐catalyzed asymmetric dihydroxylation (AD) to give the desired 12,13‐diol intermediate required for the total synthesis of amphidinolide T2 in 16 linear steps in 8.0 % overall yield.
RCM + AD = T2:在存在C16-亚甲基的情况下,区域选择性闭环复分解(RCM)形成了(12 E)-环内双键,该双键经过Os催化的不对称二羟基化(AD)得到所需的12以16个线性步骤全合成Amphidinolide T2所需的,13-二醇中间体,总收率为8.0%。
