A 2,3-secotriterpenoid with a methylketone was prepared from 1-hydroxyiminodihydrobetulonic acid methyl ester via a Grignard reaction followed by a Beckmann rearrangement. Functionalization of it led to the formation of 3-hydroxy- and 31-bromo-substituted derivatives; intramolecular cyclization, to the formation of a five-membered ring A with an alkene-nitrile. The synthetic products included compounds (5a and 9) with moderate cytotoxicity (IC50 25.22–46.66 μM) against MCF-7, HCT116, A549, and PC-3 cancer cells.
