| biological activity | Cyclohexaneacetic acid is a perfume ingredient. |
| production method | 1. preparation method: add palladium acetate 4.5mg(0.02mmol),1,4-bis (diphenylphosphine) butane (dppb)17mg(0.04mmol),5.0mmol formic acid and 5mL dimethoxyethane into a pressure reactor. Methylene cyclohexane (2)24mg,(2.5mmol) is added, and carbon monoxide gas is introduced until the pressure reaches 0.68Mpa. Heat to 150 ℃ and stir for 16h. Cold to room temperature, open the reactor. The solvent is evaporated under reduced pressure, and sodium hydroxide solution is added to the residue to dissolve it. Ether extraction, water layer acidified with hydrochloric acid. Ether extraction 3 times, combined with ether layer, anhydrous sodium sulfate drying. Concentrate to obtain compound (1) with 94% yield. The following compounds can be synthesized by similar synthesis methods (table I-8-5, reference book 422 pages). [1] |
