Abstract
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.
Claims20
A process for the production of a dihydronepetalactone of formula (II) comprising hydrogenating a nepetalactone of formula (I) according to the following scheme:
- in the presence of a catalytic metal that is not nickel, platinum or palladium.
A process for the production of a dihydronepetalactone of formula (II) comprising hydrogenating a nepetalactone of formula (I) according to the following scheme:
- in the presence of a catalytic metal selected from one or more members of the group consisting of nickel supported on a catalyst support, elemental platinum, platinum supported on a catalyst support, palladium not supported on a catalyst support, and palladium supported on a catalyst support that is not SrCO3.
