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

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 t
