%X 2,4-Diaryl-5,5-dimethyl-1-pyrroline 1-oxides (5)-(7) undergo smooth oxidation by concentrated nitric acid in acetonitrile to give the hydroxy  ketones (9)-(11). Reduction of compound (10) with sodium borohydride gives the diol (22), which can be dehydrated to the oxo  nitrone (23). The stereochemical assignments of the alcohol (8) and the diol (22) are discussed.
