The known pyrrolizidine alkaloids trichodesmine, trichodesmine N-oxide, lindelofine, and trichelanthic acid were isolated from Rindera oblongifolia for the first time. The absolute configurations of the chiral centers of trichodesmine, which contains an 11-membered macrocycle, were established as 7R,8R,11R,12R,13R by an X-ray crystal structure analysis. A study of the conformation of trichodesmine showed that the nature of intra- and intermolecular H-bonds and packing factors were decisive in realizing one conformer or another of the 11-membered macrocycle.

A simple and efficient synthesis of cis- and trans-myrtanic acids in preparative yields of 54–58% and 72–74%, respectively, was proposed and consisted of oxidation of cis- and trans-myrtanols by CrO3–AcOH upon addition of the oxidant to a solution of the starting alcohols at room temperature. Tests of the obtained compounds for antifungal activity showed lower activity for the quaternary salts than for the starting acids and greater efficacy for the cis-isomers than for the trans-isomers. However, the alcohols themselves, i.e., cis- and trans-myrtanols and (–)-myrtenol, had the greatest activities.
