Friedelin(I) was oxidized with oxygen in the presence of potassium t-butoxide. After neutralization and methylation of the reaction mixture, five compounds, (II), (III), (IV), (V) and (XI) were isolated and characterized. Several potential intermediates of the oxidation, (XXVIII), (XXIX), (XXX) and (XXXI) were also subjected to the oxidation on the same reaction condition and the reaction products, (II), (III), (V), (VI), (VII), (IX) and (X) were separated and characterized. Some of the interesting aspects of the reaction were discussed. It is noteworthy that friedelan-2,3-dione,(XXVIII) is not formed during the oxidation of (I), and that formations of (II) and (V) include fission-recyclization process.
