decalin segment 6 required for the total synthesis of popolohuanone E (1) was efficiently synthesized starting from the enantiomerically pure (−)-Wieland-Miescher ketone derivative 9; the method features ortho ester Claisen rearrangement of 15 and Ir-catalyzed hydrogenation of 17 (Scheme 2). Furthermore, by employing 6 as the key decalin segment, the first total synthesis of natural (+)-arenarol (2) related
总合成popolohuanone E(1)所需的顺式十氢萘片段6是从对映体纯的(-)-Wieland-Miescher酮衍生物9开始有效合成的;该方法的特点是15的原酸酯Claisen重排和17的Ir催化加氢(方案2)。此外,通过采用6作为关键十氢萘片段,以对映选择性的方式完成了与拟议的1的生物遗传前体有关的天然(+)-芳烃(2)的第一个全合成(方案3)。
