โœฆ Synopsis

IN an earlier communicationl, we reported on the structure elucidation of hardwickiic acid (I) and some other related diterpenoids, all constituents of the oleo-resin of Hardwickia pinnata. However, biogenetic considerations were invoked for the placement of the angular methyla as shown in I. We now provide experimental support for the location elucidate the absolute stereochemistry at the provides conclusive evidence for the absolute acid. describe degradation work, designed to of these quaternary methyls, as also to various asymmetric centre8. This work stereostructure II for (-)-hardwickiic
