Abstract
The title compound, namely (2'S,3'S,3aR,5'R,6aS,9R,9aS,10aR)-1,3a,4,4',5',6a,7,8,9,9a,10,10a-dodeca-hydro-9-hydr-oxy-3',9,10a-trimethyl-5'-(2-methyl-propen-1-yl)-7-oxospiro[dicyclo-penta-[a,d]cyclo-octene-3(2H),2'(3'H)-furan]-6-carbaldehyde, C25H36O4, displays phytotoxic behaviour that may be correlated with some structural features of the mol-ecule. The eight-membered ring of the terpenoid tricyclic skeleton is cis- and trans-joined with the fused five-membered rings. One intra-molecular O center dot center dot center dot HcO hydrogen bond and two inter-molecular C-H center dot center dot center dot O hydrogen bonds are present.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
