| titleOfInvention | A kind of aldehyde-ketone condensation catalyst and its preparation method and application |
| abstract | The present application relates to the technical field of biochemical medicine production, and more particularly, to an aldehyde-ketone condensation catalyst and its preparation method and application. The aldehyde-ketone condensation catalyst is made from raw materials comprising the following parts by weight: 8-12 parts of hydroxyproline, 15-25 parts of deionized water, 5-50 parts of carrier, 40-60 parts of organic solvent and 0.8-1.2 parts of acidic catalyst The preparation method of the aldehyde-ketone condensation catalyst is as follows: (1) preparing the hydroxyproline carrier; (2) preparing the aldehyde-ketone condensation catalyst base solution; (3) preparing the aldehyde-ketone condensation catalyst preparation solution; (4) preparing the aldehyde-ketone condensation catalyst Catalysts; aldehyde-ketone condensation catalysts can be used to catalyze condensation to obtain neuraminic acid derivatives. The aldol-ketone condensation catalyst of the present application, the preparation method and the application thereof all have the effect of increasing the yield of the neuraminic acid derivative. |
