A novel synthesis of guaiane sesquiterpenoids based ontrans-3-isoprenyl-2-(2-methoxycarbonylethyl)cyclopentanone

摘要

Synthesis of six guaiane sesquiterpenoids was performed starting from the title cyclopentanone. The structures of the sesquiterpenoids were confirmed by spectral methods. X-ray analysis of the key hydroazulene precursor was carried out.
