first asymmetric total synthesis of synerazol, an antifungal antibiotic, has been accomplished, allowing determination of its absolute stereochemistry. A more practical second generation route was also established. The key steps are racemization-free deprotection of a TIPS group and introduction of a methyl ether by DMD oxidation of the benzylidene moiety in a substrate having a small protecting group
通过合成两种可能的非对映异构体,已经完成了抗真菌抗菌药合那唑的首次不对称全合成,从而可以确定其绝对立体化学。还建立了更实用的第二代路线。关键步骤是TIPS基团的无消旋脱保护和通过DMD氧化具有小的保护基团的底物中的亚苄基部分来引入甲基醚。
