摘要

A-Secolupane nitriles with an aldehyde group or methylketone fragment on ring A and a cleaved C2–C3 or C3–C4 bond were synthesized via Beckmann reactions of oxime derivatives of dihydrobetulin and dihydrolupeol. A predictive analysis of the biological properties using the online PASS service indicated the synthesized triterpene derivatives were promising as antitumor agents.
