  Studies toward the Total Synthesis of Popolohuanone E:  Enantioselective Synthesis of 8-O-MethylpopolohuanoneE

  摘要：

  [GRAPHIC]8-O-Methylpopolohuanone E (2) was synthesized in a highly convergent manner starting from the cis-fused decalin derivative accessible from the (-)-Wieland-Miescher ketone analogue. The synthetic method features a biogenetic-type annulation of the phenolic and quinone segments to regioselectively construct the central tricyclic ring system as the key step.
