Abstract

(E)‐ and (Z)‐3‐(2‐butenyl)‐2,4,4‐trimethyl‐2‐cyclohexen‐1‐one 1 and 2 have been isolated from an absolue of Osmanthus Fragrance Lour. and a fusel oil concentrate. Structural proof for these compounds has been obtained via their synthesis from β‐ionone. The key step in this synthesis is the regio‐specific oxidation of 1‐(2‐butenyl)‐2,6,6‐trimethylcyclohexene.
