✦ Synopsis

The absolute stereochemistry of rubiginones Al, A2, Bl, B , Cl and C2 has been established by NMR spectral analysis using the 0-methylmandelate met od. t A facile photoinduced oxidation of rubiginones Al, Bl and Cl to rubiginones A2, B2 and C2, respectively, is discussed in relation to the absolute stereochemistry.
