The enantioselective synthesis of aromatic bisabolanes, such as 1,3,5-bisabolatrien-7-ol, peniciaculin A and B, and hydroxysydonic acid, has been described. Our methodology for the total synthesis of aromatic bisabolanes involves the stereoselective construction of the C-7 stereogenic center via a Sharpless asymmetric dihydroxylation reaction, followed by a SmI2-mediated Julia olefination. Preliminary
已经描述了对映选择性合成芳香族红没药烷烃,例如 1,3,5-bisabolatrien-7-ol、peniciaculin A 和 B 以及羟基辛多酸。我们的芳香族红没药烷全合成方法涉及通过 Sharpless 不对称二羟基化反应立体选择性构建 C-7 立体中心,然后是 SmI 2介导的 Julia 烯化。还描述了对 1,3,5-bisabolatrien-7-ol 的气味评估和对青霉素 A 和 B 的绝对构型的确认所获得的初步结果。
