Resumen:
The mass spectra of [17-13C]phyllocladene and [3-13C]methylenecholestane have been examined. It is shown that there are some rearrangements at 70 e V as in the case of [17-13C]kaurene. However, no extensive randomization is evident at the molecular ion level. The results are interesting because very little is known about 13C randomization in polycyclic aliphatic hydrocarbons. The percentage retention of label was calculated for each ion. Copyright © 1977 Heyden & Son Ltd.
