Joint ozonolysis of cyclomusalenone O-methylketoxime and methyltrifluoromethylketone formed stereoisomeric triterpene 1,2,4-trioxolanes and N-methoxylactam. The structure of (24S)-24-methyl-29nor-cycloart-3,25-dione, which was obtained from ozonolysis of cyclomusalenone, was established by an x-ray crystal structure analysis.
