especially noteworthy in providing a betulin-derived amine dimer. Other unexpected synthetic results included the 11 and 13/14 → 17 conversions, which yielded an imidazo derivative. X-ray crystal structures of dimer 12 and intermediate 25 are reported. All of the betulin modifications were examined for anticancer activity against the P388 murine and human cell lines.
