The partial oxidation of sophoradiol (olean-12-ene-3β(e), 7α(a)-(or 22β(a))-diol) with chromium trioxide-pyridine complex affords sophoraon-3-ol. Analysis of its rotatory dispersion curve confirmed the appropriateness of the conclusion*1 that, of the two hydroxyls in sophoradiol, one is at C-3 and the other should be at C-22 or C-7.
