Article abstract of DOI:10.1016/S0040-4039(00)88519-6

The absolute stereochemistry of rubiginones A1, A2, B1, B2, C1 and C2 has been established by NMR spectral analysis using the O-methylmandelate method.A facile photoinduced oxidation of rubiginones A1, B1 and C1 to rubigignones A2, B2 and C2, respectively, is discussed in relation to the absolute stereochemistry.
