The lithium aluminium hydride – aluminium chloride reductive cleavage of norcamphor ethylene ketal yields 2-(2-endo-norbornyloxy)ethanol in ≥98% yield, whereas the similar reduction of camphor ethylene ketal gives 2-(2-isobornyloxy)ethanol in 78% yield and 2-(2-bornyloxy)ethanol in 22% yield. These are the products arising from steric approach control.

A novel route to the zizaane sesquiterpene skeleton is demonstrated with a nine-step synthesis of (±)-isokhusimone (2) from norcamphor in an overall yield of 35%. This constitutes a formal synthesis of (±)khusimone (1).
