โœฆ Synopsis


The diterpene hydrocarbon rimuene first isolated by McDowall and Findlay (I) from the essential oil of Dacrydium cupreseinum (rimu) has been the subject of a number of structural investigations (2,3,4,5,6). The proposed structure (3,4) has been shown by recent synthetic work (7) to be incorrect. Earlier investigations had established that rlmuene ha8 the usual perhydrophenanthrene skeleton with a genimal dimethyl group at C(4), vinyl and methyl group8 at C(13) and a triaubstituted double bona.

The constitution of rimuene has been the subject of protracted controversy in recent years and indeed represents an outstanding unsolved problem in diterpene chemistry. Our recent interest in the constituents of Erythroxylon monogyuum (1) has caused us to re-e xamine the published evidence on rimue
