The small positive NOEs found in most small and medium-sized molecules are difficult to detect reliably by nuclear Overhauser and exchange spectroscopy (NOESY). partly because of sensitivity problems exacerbated by long relaxation delays needed between experiments: Morris G. A., Magn. Reson. Chem., 24, 371-403 (1986). Therefore, NOE difference spectroscopy instead of NOESY was used to determine NOEs in synthetic (±)-1 and natural dictamnol.

Preparative GC at 120 °C of the essential oil of the leaves of Amyris diatrypa SPRENGEL provided an almost pure sample of pregeijerene (7). At temperatures>120 °C Cope rearrangement to geijerene (9) took place. For example, see: Kubeczka K.-H., Phytochemistry, 13, 2017-2018 (1974).
