Abstract
The present invention provides a novel method for chemoselectively hydrogenating cyclic monoterpene precursors with reduced PtO2 at low temperatures, to yield products in which the alkene groups are saturated while the cyclopropane rings from the parent hydrocarbons are conserved.
Claims16
A method for the chemoselective hydrogenation of cycloalkene, comprising
- obtaining a cycloalkene having at least one alkene group and at least one cyclopropane group;
- and,
- hydrogenating the cycloalkene with a catalyst;
- controlling the degree of hydrogenation through temperature;
- wherein the at least one alkene group is saturated and the at least one cyclopropane group is conserved.
