RP-HPLC analysis of DMC autoxidation products. (A) 100 μl of a reaction of 50 μM DMC in 1.5 ml 10 mM NH4OAc buffer pH 7.5 were injected at 48 h reaction time without prior extraction. The chromatogram was recorded at UV 205 nm using a diode array detector. The inset shows the UV spectrum of peak 1a recorded online during HPLC analysis. (B) Selected carbon chemical shifts and HMBC correlations (arrows) of demethoxy-bicyclopentadione diastereomer 1a.
