✦ Synopsis

IN a previous paper' evidence for the constitution of the main naturally occurring crystalline diterpenes was summar ized, while in a later paper2 evidence was adduced for their absolute configuration. No direct chemical proof was given for the constitution of rings A and B nor for the position of the angular group which, on biogenetic grounds, was placed on C-12 although its position on C-11 could not theoretically be excluded.

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. Ear

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
