Abstract

[structure: see text] Three novel tetranortriterpenoids, cipadesins A-C (1-3), were isolated from the aerial parts of Cipadessa cinerascens. They possess a novel carbon skeleton, in which rings A and C were joined via C-10 and C-11. Their structures were elucidated by spectral evidence. X-ray crystallographic analysis confirmed the structure of 1.
