Total Synthesis of Clavukerin A and Its Epimer

Enantioselective synthesis of clavukerin A and its epimer was carried out.By the comparison of the spectral data and specific rotations of synthesized and natural ones, two trinorsesquiterpens isolated from Clavulia and Cespitularia species are confirmed

Total Synthesis of (+/-)-Clavukerin A: A New Trinorguaiane Sesquiterpene. Biomimetic Synthesis of (+/-)-Clavularin A from (+/-)-Clavukerin A

(+/-)-Clavukerin A, 2,8-dimethylbicyclodeca-5,7-diene, was first synthesized utilizing thermal cycloaddition and two carbon ring expansion reactions as key elements. (+/-)-Clavukerin A was transformed, via photooxidation mimicking the biogene
