(+/-)-Clavukerin A, 2,8-dimethylbicyclo[5.3.0]deca-5,7-diene, was first synthesized utilizing thermal [2 + 2] cycloaddition and two carbon ring expansion reactions as key elements. (+/-)-Clavukerin A was transformed, via photooxidation mimicking the biogenetic reaction, into (+/-)-clavukerin C, which was further rearranged into (+/-)-clavularin A by acid catalysis.
