Abstract:
Reaction of cyclic and acyclic monoterpenes with acetonitrile under Ritter type conditions was investigated. An unusual tendency to obtain racemic 8-acetamido-2,4,4,8-tetramethyl-3-aza-bicyclo [3.3.1] non-2-ene perchlorate was observed in all cases regardless of the starting terpene. It is worthy to pointing out that when linear terpenes were used, the reaction is believed to follow a biomimetic pathway forming cyclic cationic species before reacting with the nitrile to form the same byciclic frame. If 3,5-ditrifluoromethylbenzonitrile was employed the corresponding isobornylamide derivative was obtained instead. © 1995 Elsevier Science Ltd.
