| titleOfInvention | Preparation method of decanisoprenol |
| abstract | The invention discloses a preparation method of decanisoprenol. The method comprises the following steps: in a system of tetrahydrofuran and toluene solvents, using available acetoxyethlydiethyl phosphate or triethyl phosphate and taking sodium hydroxide or sodium ethylate, solane-copper to produce acetic decanisodialyklene ester or decanisodienoicacid ethyl ester; hydrolyzing by using sodium hydroxide or reducing by using lithium aluminium hydride/aluminum chloride; and hydrolyzing to obtain the product decanisoprenol. The invention has the advantages of easily bought raw materials, simple manufacture and mild reaction. Severe conditions of synthetic route of decanisoprenol desulfonylation and mercury toxicity pollution caused by using Na/Hg for reduction are avoided, and expensive and hard available diisopropyl lithium aluminium or dissobutyl lithium aluminium as a reductant is also avoided from utilization so that the synthesis becomes simple and feasible, the yield is high, the cost is low and industrial production is facilitated. |
