| titleOfInvention | Method for chiral synthesis of levorotatory menthol |
| abstract | The invention discloses a method for chiral synthesis of levorotatory menthol. In the process, dextrorotatory pulegone is used as a starting material; catalytic hydrogenation is carried out on the dextrorotatory pulegone by a chiral rhodium catalyst to generate levorotatory menthone; and the catalytic hydrogenation is carried out on the levorotatory menthone by a chiral ruthenium catalyst to synthesize the levorotatory menthol. In the process for synthesizing the levorotatory menthol through an asymmetric synthesis technology, the yield of the levorotatory menthone is more than 90%, the ee value of the levorotatory menthone is more than 99%, the total yield of the levorotatory menthol is greater than 83%, the ee value of the levorotatory menthol is greater than 98%, and the specific rotation is from-49 degrees to -50 degrees. The synthetic process is simple and is suitable for industrial production of the levorotatory menthol in a large scale, and the prepared levorotatory menthol has the advantages of high yield, good selectivity, high catalyst activity and other characteristics, is simple to recover. |
