| titleOfInvention | Method for preparing DL-3-methyl-cyclopentadecan-1-one |
| abstract | The present invention is to proceed with the ketalization reaction while removing the water produced by heating the compound of the formula (II) as a starting material under anhydrous benzene, acid catalyst using anhydrous salt, and after completion of the reaction, a non-polar or low-polar organic solvent The compound of formula (III) was prepared by reaction with phenyltrimethylammoniumtribromide (PTT), and the strong base was reacted under anhydrous dimethyl sulfoxide to react with a strong base at room temperature. The compound of formula (VI) prepared by using para-toluenesulfonic acid hydrate as an acid catalyst in acetone and water at room temperature was reacted with a cuprous iodide and methyllithium in anhydrous ether at -20 ° C to 0 ° C. It relates to a method for preparing the compound of formula (I) in high yield, high purity without a separate purification process. |
