The structure of the tran -clerodane dicarboxylic acid haplociliatic acid (62), obtained from Haplopappus ciliatus, was established by X-ray analysis. The presence of the known diterpenoid cw-kolavenic acid has been noted in several members of the tribe Eupatorieae. Some cw-clerodanes [e.g. (63)] have been obtained from the Brazilian Compositae, including Symphiopappus itatiayensis. [Pg.114]

The widespread occurrence of the clerodane skeleton is exemplified by the isolation of (—)-hardwickiic acid (25), the C-15 monomethyl ester of kolavenic acid, and two furanoid substances, agbaninol (26, R = H) and agbanindiol B (26, R = OH) from Gossweilerodendron balsamiferum (Caesalpiniaceae). Agbanindiol A has the structure (27). These compounds have been correlated with kolavenic acid and hardwickiic acid. [Pg.129]

Structural correlation of solidagonic acid with 495 and 475 was made feasible by the recent assignment by Misra and coworkers 391) of absolute stereochemistry to the chiral centers of the Hardwickia pinnata clerodanes, (-)-hardwickiic acid (511), kolavenic acid, and kolavenol (Figure 34 [p. 515]). Their pivotal work on clerodane stereochemistry proceeded as described below ... [Pg.493]
