초록

Singlet oxygen-mediated photooxidation and subsequent triplet oxygen insertion of 11-hydro-13-(methyloxy)carbonylartemisinate (4) yielded a diketo compound 5 as the major product instead of the expected 11-hydro-13-(methyloxy)carbonylartemisinin (6). The formation of the unexpected product was in part consistent with the mechanism proposed by Acton and Roth and is the first isolation of the diketo compound from the photooxidation of artemisinate.
