| titleOfInvention | Synthesis process of trans-menthyl-2, 8-diene-1-alcohol |
| abstract | The invention belongs to the technical field of preparation of trans-menthyl-2, 8-diene-1-ol, and particularly relates to a synthesis process of trans-menthyl-2, 8-diene-1-ol. The synthesis process comprises the following steps: (1) 1, 2-epoxy limonene is prepared by taking limonene as a raw material and catalyzing and oxidizing the limonene by lipase; (2) the 1, 2-epoxy limonene is opened to form limonene selenide in the presence of sodium borohydride and diphenyl diselenide; (3) the limonene selenide forms selenium oxide under the action of an oxidant, and then elimination reaction is carried out to prepare trans-menthyl-2, 8-diene-1-alcohol. According to the invention, 1, 2-epoxy limonene is prepared firstly by a lipase catalysis method with high chiral selectivity, and the purity of a reaction intermediate is improved without a complex purification process, so that the chiral purity of a final product trans-menthyl-2, 8-diene-1-ol is improved. |
