Cladogynos diterpene guaiane sesquiterpene chettaphanin I crystal structure
Abstract
Four new ent-halimane diterpenes (1-4) and one new guaiane sesquiterpene (5) were isolated from the CHCl3 ext. of the roots of Cladogynos orientalis, together with six known compds. The structures of compds. 1-5 were established using spectroscopic methods, and the stereochem. of chettaphanin I (6) was confirmed by X-ray crystallog. [on SciFinder(R)]
