CONFORMATIONAL ISOMERS OF 14-HYDROXY-9-EPI-β-CARYOPHYLLENE ISOLATED FROM THE WOOD OF JUNIPERUS OXYCEDRUS

Article abstract of DOI:10.1016/S0040-4039(00)95172-4

A nwe sesquiterpene alcohol has been isolated from the essential oil of the wood of Juniperus oxycedrus L. and indetified through its spectroscopic properties as 14-hydroxy-9-epi-β-caryophyllene.Dynamic 1HNMR measurements have revealed two major conformational isomers in roughly equal amounts at room temperature, with an interconvertion barrier of 17.5 Kcal/mol.
