The present invention provides substituted puleganic amides and compositions thereof, which are both useful as a topical treatment for skin, such as a repellant for insects and arthropods.
Dihydronepetalactone, a minor natural constituent of the essential oil of catmints (Nepeta spp.) such as Nepeta cataria, has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, which also has fragrance properties, may be used commercially for its insect repellent properties.

This invention relates to a process for hydrogenating nepetalactone, utilizing a metal catalyst that is optionally supported, to yield dihydronepetalactone. A suite of supported catalytic metals lead to rapid hydrogenation and high selectivity for dihydronepetalactone.
Disclosed are methods for treating catmint oil. The treated catmint oil can be used for the production of hydrogenated catmint oil, which is enriched in the insect repellent, dihydronepetalactone.
