Reaction Steps

A mixture of 1000 parts of trans-1,2-limonene oxide, 4 parts of zinc octoate (contains 18% zinc) and 2 parts of 2-aminophenol was refluxed at 200-226° C. for 3 hours in a three-necked flask equipped agitator, Dean-Stark trap, and temperature probe. After cooling 998 part of the mixture containing 67% carveol and 8% carvone was obtained. This mixture can be further processed to carvone according to example 58, or fractionated to obtain pure cis-carveol.
