ResumoA new diterpene acid, isolated as its methyl ester from Callitris columellaris F. Muell., is shown to be Δ13(17)-communic acid. Another new isomer of communic acid is shown to result from thermal rearrangement of trans-communic acid methyl ester on gas chromatography, and is tentatively assigned the structure methyl labda-8(14)-trans-11(12)-cis-13(15)-trien-19-oate on the basis of spectroscopic and mechanistic considerations.
